It's always nice to know there are alternatives to any given situation.

I like the alternative approaches.

In the alternative, they think they won't be able to get it, they will be turned down as a tenant, will have wasted the application fee and one more person in the world will think of them as a loser. 

@Nicholas Flatoff I think @John Woodrich's recommendation of looking into alternative financing and seller financing is a great idea.You could also partner with someone who has some income to get the job done.

@Dave Foster , I see what you mean about using a 1031 to buy some alternative form of passive, cash producing real estate. 

They said wait,   I said no way and lobbied for an alternate resolution and got one. 

There are now private market flood alternatives (not part of NFIP) that may or may not be better or less expensive. 

Also, without knowing your capabilities this is much higher risk than some alternatives. 

alternatively, is there a place where a landlord can query a database for such "bad tenants" again not talking about normal credit check or background check.thanks!!

If you are leaving money on the table "because it falls slightly below the 70% rule", then you missed the point.Ultimately, it depends on what the opportunity cost is: If you flip a house bought at 80% of ARV, that's great if your alternative (the opportunity you're giving up) is doing nothing.
