If they own their own business etc, often just a quick look at their website is enough to know if their business is on a sound footing or a fly by night operation.   

Had a 1 bedroom house about 600 square foot that I detailed to 'nice' condition.

But, in that case, he is back to square one as a target for retaliation. 

While living upstairs i had high electric bills winter only (all elec apts) like 300$ avg in winter time when running heat at about 65ish.I have a feeling the furnace size is pushing it, not incredibly small and not oversized for the unit about 1100 square feet.

I was nervous as all heck at him even setting foot on my property.

I don't know that we have the proformas on those anymore, it's been a while.How many buildings are you planning on building, and total square feet?

While some may go for the idea, I would not touch it with a 10-foot pole for reasons already mentioned above, mainly potential damages to the home.I also would not like the potential drug activity that could arise from this.To each his/her own.My current lease agreements offer garden spaces to tenants, but prohibit any growth of Marijuana.

Take for example the "related group" Miami's largest condo developer, they set their prices for their new project "Auberge" at an average of $600 per square foot compared with the $850 per square foot it might have asked a couple of years ago.

I'm not familiar with your market but if you're putting in free standing claw-foot tubs in mansions then we may be talking apples and oranges.
