I got a few probate leads from the courthouse, but I'm not sure if I should contact anyone before ascertaining if there's a house available.

But what we can also ascertain from this chart is from 1980 to 2000, supply most likely grow with demand (or purchasing power) which was driven by sustainable fundamentals.  

And I was not able to ascertain your seller (park or private) but if private they've already paid their lot rent for this month (unless delinquent) so it's usually not a stretch to date a contract/option to the end of the month to "make a clean sale".And after re-reading your last post, yes if you intend to owner finance you'll want to hire a "licensed mortgage originator" or an "attorney" to close the deal for you.

If so: 1)Find out whether you have been sold a Surplus Line Insurance product and contact the Department of Insurance and Financial Services within the state your properties are located to ascertain whether NREIG/AGM hold a license to be selling a Surplus Line Product, despite having you signing up to the Membership Agreement.

Try to ascertain how motivated a seller he is... why is he interested in selling at this time?

Not interested in building it myself, as certainly I do not have the experience or ordering power that a builder does, as you point out.

PS: You should have done your own homework first to ascertain what type of rent you can reasonably collect in this type of unit for your area, irrespective of what the owner says he gets from these tenants.

I don't like that strategy either, with the exemption of major items that could not be ascertained from an initial walkthrough.

There are certain structures that will still qualify for tax-deferred exchange treatment as long as certain conditions are met. 

Perhaps the established wholesaler with personal connections to real buyers who can accurately ascertain whether a deal can be done quickly is performing a service for sellers.
