I have all kinds of specific searches set up for my investor clients to help find the best deals. 

Firstly I apologize that I do not have any market insights data specifically, but Houston has been a rough market as valuations have pulled back.

On a positive note we did build a new house to the specifications of a specific tenant. 

Specifically, Texas has some of the highest insurance and property taxes in the nation, but the appreciation makes up for those high costs in the long run.

Well even if the rent is equal to the mortgage, you'll still be in the negative after repairs, CapEx, vacancy, etc.Why would you specifically be thinking of investing at a negative cash flow?

In our case, we are focused on Northern Virginia (specifically Alexandria, VA).

This is not specific tax advice.  

Feel free to connect if you have any specific questions about, but this is the best general advise.

I would imagine the bigger loan origination companies out there who underwrite like robots because they are lining up the sale before closing  will be the exception and require those docs up front. 

The two things that will determine the listing when you go to list for your specific house, it is price and condition.
