@Grant GriffithsI'd keep looking into that lease option (contract sell) type of stuff.On the feedback: the possible correctable ones I see there are:Plant a cheap row of young plants that way at least when the concern of backing to an apartment comes up, you can play up the long term that there will be a privacy hedgerow.The other two concerns I doubt you can do much about at this point.Good luck.  

However, I am not sure if this is correct, as another website I found said 35 sqft per child.

The only issue with a flat roof would be pooling water if not done correctly or the potential of cave in if you're in a snowy climate.

I just wanted to make sure legally I was following the correct guidelines.

@Ben MiculobIf I understand the question correctly, what you're looking to do is "refinance" before the hard money loan term expires.

@Barbara GarrettI've never done wholesaling, but if I understand the concept correctly, I think you would want to get the property locked up in a contract to buy before you try to sell it.

All of them are going to be cash only buys correct?

This would inform the tenant they’re in violation of the lease and must correct the violation or leave.

I don't think it is correct to presume that taxpayers pay more if someone creates a new Section 8 property. 

You line up a HML - so the next time you find a "deal" you use the hard money to buy the place, fix it up, and if the numbers are all correct and you are still under 80%LTV then you refinance into a conventional loan and payoff the hard money and construction loans.Keep doing wholesale deals, since this will give you some credibility with the hard money lenders, and you will need some of your own cash for the down payment and construction costs.
