I recommend focusing your attention on sourcing great real estate rather than allowing the creative financing be the tail that wags the dog.

I'm looking for a new source of investors who are in the business of funding these deals.  

@Saul Vargas, to piggyback off others, sourcing a traditional SFH rental that meets your underwriting criteria will be complex due to interest rates and market conditions.

Calling a FSBO wasn't the original question - it was "text blasting".I cited some very solid sources above that are worth reading. 

Recommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.

The returns will likely be greater if you source the borrower and originate on behalf of the IRA.

Yes, Evan Conner has been an excellent source for us in the Ozarks area of Missouri.

The data @Devin Conley posted is pretty solid from my experience (I do not know Devin nor how he sourced the data, just going by my own investing experience).  

Anyone have any good referrals for any of these sources that are geared toward or accommodate investors?

It sounds intriguing and like it could be a another good source from homes since the MLS has been pretty dry lately/hard to make houses pencil out for flips.Is buying from auctions a good idea?
