They may not be able to qualify for the financing for up to three months after the first transaction.I have a few local sources that might fund this depending on the specifics.  

Won't qualify for fannie or freddy insured loans due to number of financed properties.

I always need to sleep over a big decision for at least 2 days, however I feel like I'd lose a very qualified tenant who's actually willing to pay higher given the hot market one of my properties is in. 

Seller avoids the foreclosure so they can qualify to buy a home sooner.

(note: I am living in Roseburg, OR right now, but as a travel therapist, will be moving to WA very soon)

It's only been about a week, haven't had one qualified tenant so far. 

If a mortgage lender says I qualify for a loan with a reasonable APR, then I should be better off taking a loan for a home instead of owner financing?

There's no way I could qualify for $220,000 right now.

The best times to show units are whenever qualified tenants want to see the units you have for rent.Rental real estate is a very impulse type thing for a tenant. 

If you have minimal or no other debt you should be able to qualify even with a lower income.
