If no credit score, you can still get an FHA loan using alternative credit, such as rent payment, insurance payment, mobile phone payment, utility bill payment, etc, but you will need to find an FHA approved lender who will accept alternative credit. 

Appreciate any insights into alternative financing or input if what we have in place is "ok" for this type of property.

Do you have an alternate source of financing?

OR the alternative, take some appraisal courses and learn the methods. 

We have only purchased apartment complexes thus far (1,500+ units), but have strongly considered alternative investments like mobile home parks, as long as the numbers make sense.

Instead of waiting for retirement and buying then, you can just buy today for much less money and you can get the property pay for itself through rentals and you can use the property for your holidays.And, if you happen to change your retirement plans in the meantime, no worries you can sell for a nice profit and will have made some great rental income along the way, which will allow you to buy a nice place in your new destination of choice. 

@Jonathan AlmanzaWell you have two choices, buy now at a high price while lenders are relaxed on lending standards or wait until standards tighten up and housing prices drop.

That helps build trust.Find alternative ways to communicate.

I don't think there was any warning from their team on the choices the previous board made financially. 

Alternatively, the owners who's checks have stopped coming in from the arbitrage guys may be very keen to sell.
