I can't comment on the Houston market, but I do a lot of investing in Detroit.While I haven't personally gone and confirmed it, folks are citing the same thing happening there.

I will keep this page posted to see what comes of it,

As an out of state investor, I cannot personally manage the property, hence why I hired a PM. 

If getting the tenant out would kill the deal, would you keep the tenant ?

Personal.   

Can someone please advise me on the pro's and con's and keeping the lot as a single lot with all 14 duplexes on it or subdividing each lot to have 14 individual lots? 

Had you personally visited these properties prior to making your offers?

They fund 100% of the purchase/ rehab but keep 50-60% of the net profit.   

Someone with a large portfolio might have a system that works for them and which they have maximized but which might not translate well to your market, your personality or your approach to investing.

From years of borrowing I can also say these are the lenders who will take the time to understand obstacles that may arise on any given project and formulate solutions that keep your projects moving.
