Quote from @Khon Kounbandith: Investment Info:Single-family residence fix & flip investment.

They can qualify for a new mortgage and show they are not the ones paying on the old loan so that the payment doesn't affect their DTI.

That does not require employment or job seasoning instead it uses the rents to qualify and you can take out up to 80% LTV cash.Use the cash to put down on the next 1-2 or more properties as long as the other properties are debt servicing themselves it opens up more opportuities to buy more future assets and increase your passice income.

Are you able to move into the property and make it your primary residence?

Would the buyers/borrowers be purchasing with the intent of putting a mobile home on the property and making it their primary residence?

Even trusting a brand new GC who's licensed/"qualified" is a risk from out of state, let alone out of country.

If you have your own business/self-employed you might qualify for a Solo 401(k) or multi-participant 401k whereby you can self-direct into real estate with those funds. 

Another possibility is a cash-out refinance on your dad’s house if it qualifies, which would tie the loan directly to that property.
