I agree with all above. It can be done... just have to wrap your mind around it. There is the financial aspect of the project as well. Lets say a total of 14,000 sq ft at an average of $15-20 a square ft? Lets use $20 with a 25% profit margin. Are you going to have to sit on 210k for 90 days(60 to complete and 30 to pay if your lucky)? Or are you getting paid after each house completion?
