I have a relative that is a doctor.

Private lenders are always available, starting with people that love you, spouse, parents, relatives, and working out in your circle of friends.

I have relatives who have helped people to get Mods and if they werent successful they usually got a listing.

I haven't done many sales to VA buyers (just because VA buyers make up a relatively small buying segment), so I don't know how VA underwriters do things.

If it was in good physical condition, then probably:The loan payment was just too high relative to where market rents are, and they had no reserves.

I've looked at possible expenses related to this, but wonder if there is a 'simple formula' to quickly vet the potential of a property?

Yes, I've compared the property to recent sales and I realize that by itself, the current value compared to the bubble value is about as useful as comparing the relative bubble/current value of a property in California to a bubble/current value in a Florida submarket.

I plan to spend my attention on sfr and multi-family over next yearI have consider northwest of Milwaukee for buy-hold since I have a ton a relative in that areaThis my personal current breakdown of SFR~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~buy-hold / wholesaling -> northwest of Milwaukeerehab / wholesaling / buy-hold -> suburbs This my personal current breakdown of Multi-family ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~buy-hold / wholesaling / rehab -> suburbsbuy-hold / wholesaling -> Milwaukee depends on zip code / areajust my opinions

I have never been to the island yet, some of my relatives reside there or visit.

As I'm gaining more experience in investing and learning more I wonder what opportunities are out there for other related fields that could boost my skills as an investor.
