I took a 750 foot house and tripled the size with an addition.

Or what you would expect to pay for around 265 square foot, 30 squares single story.  

What the cost per square foot to repair this or that will be.  

Wholesaling can be a good foot in the door, but it takes work and it will take advertising.

This angel investor doesnt ever want to step foot on the property doesnt want anything to do with it other than just a stable return on money. 

@Bob Bowling I feel we got off on the wrong foot.

Granted, these are agents were part of larger team and didn't read the fine print on their employment contract.

I suppose the short answer is contacting the local Planning and Zoning Commission to get an understanding on What mixed useage is allowed in the complex .What is your Cost Conversion per square foot if the town allows this to happen ?"

I always look up neighboring properties and get a price/sq foot of the house only (take appraised value - land and divide by sq feet). 

Others invest for appreciation but depending on the market it can be expensive to get your foot in the door.
