I have been told to stay away from lease options in Texas.

Several of the contractors offer helical piers but don’t seem to think they’d be a more cost effective option - we can directly ask about this again.  

Financing options do exist: hard money loans, renovation loans, and some traditional mortgages can be used on distressed properties if criteria are met.

There's zero reason to do this when there are plenty of options to avoid it. 

Since you want to aggressively invest in the near future, you will need cash and the 30 year option is the right one for you.

Also, within this approach, the option that attracts me the most is purchasing and installing a 'tiny home' on a campground that allows it.

The only other option I see is a short sale, if you don't need to purchase for a few years and don't mind a temporary credit hit to save the $60k.  

I do single family "off market" that I take over with owner financing, subject to, wraps and lease options.

And if it were set up where everything went through a title company so the buyer pays the title company, they manage the buyer's loan (from me), and the title company ensures my mortgage is paid without my direct involvement... what parts of the transaction would feel risky or not worth the headache to you? 

My two partners are willing to pay their share, but they’ve also offered me the option to take over the property completely since the loan is in my name.Here’s my dilemma: If I keep the property and rent it out, I could get around $2,300 in rent, but my mortgage is $3,300 at a 7% interest rate.
