Description

Real estate sales agency system and method performed by real estate agents. {Real Estate Sales Agency System and Method}

The present invention relates to a real estate sale agency method conducted by an authorized real estate agent using a real estate sale agency system,

More specifically, the real estate agency conducts sales agency practice to promote sales for sale quickly, attract sales customers, and handle the entire process from signing sales contracts to one-stop, increasing sales rates, discount rates for unsold sales, and It relates to a sale agency system and method performed by a certified real estate agent who executes a rental brokerage and quickly concludes a sale contract for sale for sale through the application of a discount rate for the remaining portion for sale and rental conversion of the sale for sale owned by the company.

We can easily come across the term “sales” in our daily life, and in order to receive sales for apartments, sales for direct use in commercial facilities, officetels, and shopping malls, or sales for investment, we collect information through various channels and conduct sales. Ownership is transferred by applying for or receiving a sale.

In this process, there are cases in which the sale price is blown, the ownership of the sale item cannot be transferred, or the sale contract is concluded at a higher price than the market price due to deceitful or fraudulent acts of some developer, sale agent, sales consultant, sales staff, etc. The reality is that the number of good victims who suffer losses from participating as members of the reconstruction project implemented by the local housing association is increasing.

In the Housing Act and the Rules on Housing Supply, the legal regulations on the supply of large-scale apartment complexes and housing of a certain size or larger are applied. Stable sales regulations have been established and implemented.

In the case of sale that is not covered by the Housing Act, the Act on Sale of Buildings applies. Officetel (30 households or more than 30 rooms), non-housing facilities and houses are built in the same building If the floor area used for purposes other than housing is 3,000 square meters or more, the total floor area is 3,000 square meters or more In the case of renting on conditional conditions, the law is applied to some extent, so there are some restrictions. The purpose of actual enactment of the law is not being achieved.

Due to this situation, unqualified sale agencies are created one after another, excessive advertising and false advertising at each building sale site, inflating the profit rate, taking temporary deposits and advance payments from personal accounts, and then fleeing, false announcements of unsold sales discount rates, and receiving money at the discount rate. , a number of pre-sale fraud and pre-sale accidents are occurring, such as signing a pre-sale contract with customers who are not eligible for pre-sale.

What is more deplorable is the fact that even a cleaning company or a painting company with no knowledge about the real estate field is residing in a new villa and consulting on sales, saying that they will act as a sales agent at a small sales site. As such, in the real estate sales market, sales are carried out on behalf of the client based on special or internal relationships, and the sales staff in charge of the sales agency do not have any qualifications and take no responsibility. It's just that you pay a fee.

On the other hand, real estate brokers are classified into real estate brokers who have qualified as stipulated in the Real Estate Broker Act and have registered for the establishment of real estate brokerage offices in the city, county, and gu offices, and those affiliated with the real estate agent who are affiliated with the real estate agent and conduct brokerage business. Including the affiliated real estate agents, about 200,000 people are performing brokerage work. Most of the real estate brokers live in or have a connection with the area where the brokerage business is opened, and they have been in the brokerage business for more than 10 or 20 years in the same place. .

In addition, Article 14, Paragraph 1, No. 4, of the Real Estate Act stipulates that real estate sales of commercial buildings and houses are the business of a certified real estate agent, and according to the Supreme Court precedent, individual real estate agents are also allowed to sell a part. Not only is the sales agency work legal, but it also has high stability and reliability, so it is possible to prevent sales fraud and accidents caused by sales staff wandering the sales site. and rapid completion of the sale can be achieved.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, it should be noted that the same components or parts in the drawings are denoted by the same reference numerals as much as possible. In describing the present invention, detailed descriptions of related known functions or configurations are omitted so as not to obscure the gist of the present invention.

In addition, the terms and methods according to an embodiment of the present invention should not be limited to the specific terms and methods, but should be applied or interpreted in an extended manner within the scope of the invention.

We can easily come across the term “sales” in our daily life, and in order to receive sales for apartments, sales for direct use in commercial facilities, officetels, and shopping malls, or sales for investment, we collect information through various channels and conduct sales. Ownership is transferred by applying for or receiving a sale.

In this process, there are cases in which the sale price is blown, the ownership of the sale item cannot be transferred, or the sale contract is concluded at a higher price than the market price due to deceitful or fraudulent acts of some developer, sale agent, sales consultant, sales staff, etc. The reality is that the number of good victims who suffer losses from participating as members of local housing associations is increasing.

In the Housing Act and the Rules on Housing Supply, the legal regulations on the supply of large-scale apartment complexes and housing of a certain size or larger are applied. Stable sales regulations have been established and implemented.

In the case of sale that is not covered by the Housing Act, the Act on Sale of Buildings applies. Officetel (30 households or more than 30 rooms), non-housing facilities and houses are built in the same building If the floor area used for purposes other than housing is 3,000 square meters or more, the total floor area is 3,000 square meters or more In the case of renting on conditional conditions, the law is applied to some extent, so there are some restrictions. The purpose of actual enactment of the law is not being achieved.

Because of this situation, unqualified sale agencies are created one after another, and excessive advertising and false advertising at each building sale site, inflating the profit rate, running away after receiving a personal account for the provisional down payment and advance payment, false notice of the unsold sale discount rate, receiving money with the discount rate, Numerous pre-sale fraud and pre-sale accidents are occurring, such as signing a sale contract to customers who are not eligible for sale.

As a result, the Ministry of Land, Infrastructure and Transport decided to comply with the qualification standards of the sale agency, and accordingly, the sales agency announced that only companies with a construction business license would be able to perform the sale as an agent, and that it would continue to crack down on it.

In accordance with the Ministry of Land, Infrastructure and Transport’s policy of prohibiting unqualified real estate sales agencies from proxy sales, 28 sales agencies obtained construction licenses and satisfied the qualification conditions, but there are more than 3,000 sales agencies in total. As concerns grew that they could not survive if they competed with each other after rushing into the real estate market, the law was amended in November 2018 to relax the qualifications of real estate agents as housing and urban maintenance companies.

However, the problem is not solved by strengthening the qualifications of the sale agency, and the reality is that there is no legal or institutional device that can control a lot more unqualified sale agencies than those with qualifications. Neither and the unqualified real estate agencies constitute a multi-level and performance-based pay system in the lower sales organization structure.

A sales agency has a single headquarters or multiple headquarters depending on the situation of the sales site to organize sales (so-called group sales). We are supplying and supplying members of

As shown in the figure above, the sales agency has a plurality of heads of departments to form an organization, and the head of the department organizes an organization with a number of team leaders as subordinates, and the team leader organizes a number of sales staff and sales staff, also known as sales consultants, to participate in sales. Necessary public relations and telemarketing, profit rate promotion and sales contract promotion are in progress.

In this process, large banners are attached to the street side of the street, illegal advertisements that violate current laws, such as advertisements on electric poles, are installed, and social problems such as sending indiscriminate mass text messages are occurring. The reality is that there are a lot of sales staff who take the comfy position that they only need to receive sales commissions by enticing and deceiving customers with exaggerated advertisements and false advertisements.

These sales staff are usually made up of relationships such as academic affiliation and delay, and they travel around the site of the sale and promote the sale. For example, 3 months at the Gyeonggi sale site, 4 months at the Incheon sale site However, since the sale site is constantly changing, you can unconditionally win the sale contract and receive the sale fee, then move to another site, or if there is a problem with the sale contract, you can change your phone number and do not bear any responsibility or obligation. As we are working in a way that we only need to receive a commission, accidents in sales contracts continue to occur.

In addition, for one sale site, the sales agency, sales headquarters, and sales team are replaced from time to time according to the progress of sales. In order to secure their profits, subordinated sales staff promotes unreasonable false advertisements and false consultations, and rather than implementing marketing measures to secure customers to receive sales, they send sales information to nearby real estate agencies by text message or It is easy to send a large number of text messages to the real estate agent's real estate agent and their affiliated agent, saying that when the customer who is attracted by the real estate agent signs a sale contract, an introduction fee is paid under the name of MGM. We are trying to accelerate the sales process.

Sales promotion texts from real estate agencies requesting to attract pre-sale customers to their real estate brokers and affiliated real estate agencies, regardless of pre-sale, unsold, or residual sale, are shown in various forms. The amount and rate are indicated. MGM is an abbreviation of Member Get Member in a dictionary term. It is a multi-level marketing term that pays a commission when a customer brings a customer. It is a means of attracting investment customers or fixed customers of real estate brokerages as pre-sale customers.

Due to the nature of the sales staff wandering around the sales site to carry out the sales work, even if problems with the sales contract arise in the future from the perspective of the sales customers who received the sales, or if they try to check the facts, it is necessary to provide them with briefings, explanations, and sales contracts. There is a serious problem that the sales staff who were promoted cannot be found.

In addition, due to abnormal signs of the real estate market and the increase in sales volume, unlicensed academies and training centers that train sales staff or educate sales staff have appeared recently, and they promote the above-mentioned deceptive and fraudulent acts, saying that they are know-how in the sales field. In the name of marketing education, it is causing many problems such as inflating profit rates and promoting methods, encouraging illegal acts such as attaching banners, and granting unauthorized qualifications.

In addition, sales employees are systematically engaged in unregistered brokerage business, such as concluding lease agreements or brokering leases for other properties, incidental to the sales tasks entrusted to them. It is a situation that causes enormous financial and psychological damage to good pre-sale customers by opening a real estate agency and carrying out both sales and brokerage business at the same time, closing the real estate agency a few months later and continuing the so-called Teotdabang business moving to another sales site. The work area of these sales staff is more serious in the case of small-scale villa sales. In the case of one villa, excluding the piloti parking lot on the first floor, if it is assumed that there are about 8 or 12 rooms, this villa is newly built, but it is not for general new sales. In spite of this, under the name of new-build sale, they are disturbing the brokerage market by using provocative phrases such as “free brokerage fee” on the website and Internet advertisements under the name of a villa sale agency. Using , ##housing, **house, etc., it is not a real estate agent and is not a real estate agent subject to the Chartered Real Estate Act, but is running a real unregistered brokerage business.

Also, for example, advertise that a villa with a pre-sale price of 250 million won can be sold for a moving-in fee of 30 million won, extracting loans as much as possible and using high-interest loans and debentures Serious fraud cases, such as deceiving the buyer and getting them to sell, continue to occur.

Even more deplorable is the fact that even a cleaning company or a painting company with no related knowledge in the real estate field is residing in a new villa and consulting on sales, saying that they will act as a sales agent at a small sales site. As such, in the real estate sale market, it is enough to receive an order for a sale for sale through a relationship with the owner, a special relationship, or an internal relationship, or to be selected as a sale agent through an open method such as bidding. It's enough if you just get it.

On the other hand, real estate brokers are classified into real estate brokers who have qualified as stipulated in the Real Estate Broker Act and have registered for the establishment of real estate brokerage offices in the city, county, and gu offices, and those affiliated with the real estate agent who are affiliated with the real estate agent and conduct brokerage business. Including the affiliated real estate agents, about 200,000 people are performing brokerage work. Most of the real estate brokers live in or have a connection with the area where they are opened, and since they have been in the brokerage business for 10 or 20 years in the same place, they are well versed in the circumstances of the region and have clear knowledge of market price information and regional characteristics.

In addition, Article 14, Paragraph 1, No. 4, of the Real Estate Act stipulates that real estate sales of commercial buildings and houses are the business of a certified real estate agent, and according to the Supreme Court precedent, individual real estate agents are also allowed to sell a part. Not only is the sales agency work legal, but it also has high stability and reliability, so it is possible to prevent sales fraud and accidents caused by sales staff wandering the sales site. and rapid completion of the sale can be achieved.

Real estate brokers who open a business place great importance on reliability because they are continuously running brokerage business in one place, and since preemptive confirmation measures are taken to prevent brokerage accidents or sales accidents, they can proceed with the sale of sales safely.

Accordingly, the applicant of the present invention solves the ills of the real estate sales agency market, and provides a quick and fast sales process, as well as a briefing on accurate information on sales and sales to customers so that they can receive sales safely. The system was applied for.
