So, I expanded markets anywhere that I could self manage from San Diego, and after a few weeks of briefly studying all the markets within a 6 hour drive, I landed my focus on Bakersfield and finding deals in traditional multi family units that needed work and were severely below market rents. 10+ offers later on everything from FHA, conventional 4 unit, the seller financing route, 5+ unit commercial lending, I finally got an offer accepted as the 2nd offer weeks after it had expired.
