Since, it's a new property maintenance is quite low and wondering if relying on Equity and Appreciation of the house over long term is right way to go? 

Can anyone make a good suggestion for a lawyer who could help with this?

As much as investors tend to complain about realtors, I'd strongly suggest that YOU need one since you sound very new to the game.

The PM brought to our attention and suggested improvments he felt were nessesary on updating each unit, after our complete renovations were done.

I second, @Wayne Brooks suggest to him that you would be willing to sign a listing agreement specific to that buyer or buyers if he has a few investors in mind that he thinks it will work for.  

I would suggest that 6% is too low which will likely make you lean further away from SFRs.

I have only tried it twice so just wondering what the more experienced investors think of this, or is this just something that people talk about to try and make a real estate investing negative seem not so bad? 

Wondering what markets people are interested in buying in right now?

I would suggest to check with your local laws first.Most likely you will need permit ( I guess you can get away without, obviously not suggesting that :D)) but possible) , also check your zoning.If not possible to create separate unit legally, I suggest not putting an oven in the basement, and rent it without, or live in it yourself

I tried using that tool earlier and it only brought up 3 suggestions.
