It's worth investigating.  

Regarding "Over the past 4 months I’ve done extensive due diligence ..." how much of that was investigating this firm?

I'm a single parent, and my professions are certified credit consultant, paralegal, private investigator(skip tracer), offline marketing consultant for business on and offline.I'm well known in the "Credit Restoration" space in east Texas and surrounding areas in getting one out of debt and increasing ones FICO Scores removing any of your inaccurate and unverifiable derogatory trade lines to receive more money for investments 4 real estate, etc., in which I have connections in getting some financing for that purpose.

I consider this my due diligence stage and so all areas have to at least be investigated and charted on a plus/minus chart.

I am just curious if there are certain things that are hard stops in the process and make you walk away without any further investigation.

But if you lack both of those, and have some cash, a HML may be your only alternative for funding a deal.I've investigated other financial source that apply more broadly than just real estate. 

My tenant  screening service which I have trusted for 9 years now qualified him through their checks, despite my investigating discovered a previous landlord reference to be inacurrate by phone number which he seemed very apologetic about.

@Eric Mulhern I'd investigate her (even just google her) and find out her problem.PS I'd drop the vernacular ("double closing") when dealing with an Official Agency;-)

Use the search feature, or better yet, investigate each of the dropdown menus. 

The basic issues I would investigate include:What type, configuration, location and rent range do they recommend?
