Could/would Mom be willing to add you to title and you both sign for a mortgage, once renovations complete?

I then went to the bank and mortgaged it for the same $30k at 8.5% over 20 years.

Once each cabin is built we would like to take a mortgage out to recover our cash and then use to build the next.

Have you worked with any mortgage brokers who specialize in FnF? 

But as of today, I am strongly considering converting it into a single-family rental because based on some Zillow comps I’ve seen I could get upwards of $8000.00 per month which is more than double my mortgage, taxes and operating expenses.

IE rent to a tenant for >12 mo,  dating before marriage, no late payments then with a down paymetn (long story here)  I'll sell on either a contract for deed (typically mobile homes on land) or a note and mortgage (regular nicer houses). 

Does your mortgage include your property tax payments?

To be able to dispose of assets when we want, to be able to sell easily (single-family homes are pretty easy to sell compared to apartment buildings), and to know that we are in control of our destiny, is worth a lot to me.Also, we can get 18 more mortgages between my wife and me before we have to worry about running out of government-subsidized financing, and hundreds of thousands in future investments before we have to worry about scale.

One thing to be aware of is the FHA multifamily self-sufficiency calculation which determines if a property can generate enough rental income to cover its mortgage payments.

Does the revenue good enough at least to cover the mortgage payment?
