Alternative way could be purchasing this property with normal conventional rehab loan, which is a standard 30 year fixed loan + rehab funds being funded up to 95% LTV.

If there's an alternative method that has worked for you, please share. 

As an alternative solution, we've placed QR codes in the units which takes people to a form they need to fill out with all the information they want to collect.

Have you thought about investing in gas and oil with about a 9 to 10 % roi.. its a 1031 exchange alternative of like kind. 

One friend of mine asked why I bought such an old truck.

I always hear the “Cap ex of 10% rule” but have yet to hear any alternatives.

It would be like putting a lien on someone's truck because they owe you pad rent.  

Your other alternative is partnering with someone who has the W-2 / who is loanable and they can make up your lack of W-2 / income.

But I always like to point out what I think may be a good alternative for small investors owning less than 5 currently mortgage properties.

It definitely depends on a lot of factors - where non-QM is generally going to be about 0.5%-1% higher in rate, but can be more than that or even lower than conventional with some more options - one in particular is if you did a longer prepayment penalty period (5 years - at a descending penalty structure or even 5% all five years), then that could drive the rate down even significantly lower than the conventional alternative.
