The idea is interesting to me but I'm not sure if it is still a profitable business model still.

Phil took my version 1 of this spreadsheet and ran with it if you'd like a sample model for a more in-depth analysis:Pro Forma Template - Small Apartments v7You should check out BP more.

Your model sounds exactly like what I did.I had a 60's split level in Murphey Candler.

Our base model will cost 85 a foot all in and sell right at 325k for 2000 sq ft. plus 66k for lot which is our all in cost on the lot. 

Given that the commission percentage model is still the norm, will give you an indication of the success of these endeavors.

@Ray Browne Ray, can you recommend a manufacturer, model number and good source for these units?

2, Should I replace in wall AC unit with a newer model or just cover the area?

I agree, systems and models are key.

I might not close 3 deals in a month but I am working on 5 to 10 million dollar transactions that take longer in scope.I could see asking that question for a buyer looking at 50k properties.Presenting low offers that are not close to market would be a NO for most busy brokers/agents.Again when you are in demand a broker/agent can set business model standards to go by.A newbie just entering the business has nothing generally so they will do a "numbers investors" bidding hoping to get some crumbs on a small sale.
