I also am not a US resident and do not qualify for conventional mortgages on my properties in the USA. 

From there, I set up appointments with anyone who has qualified.

If the seller has attorney counsel why would they feel compelled to pay a commission to a broker for doing nothing when I have already produced a ready willing and qualified buyer that can close quickly and keep the transaction very straight forward?

Anyone familiar with rental mgmt companies in and around greater Houston area (TX) that are investor friendly and can recommend to help me market, screen and place qualified tenants?

Administered by the US Department of Housing and Urban Development, it provides rental assistance for some 2.3 million qualified households annually.

I recently pre-qualified with them and was told the interest rates are all the same (6.0%).

Yes the reason I am doing a sub-to is because I don't quite qualify.

The point was about qualifying for loans. 

As for financing, on a conventional loan if you do not need the rental income to qualify then you would not need to have the property rented but if you do need the rental income to qualify then you would.  

Would this be most beneficial to present to lenders when trying to qualify, or are you stating that it would just be good for all of us to have all the number crunching written down?
