Hey Wes, My business partner and I are investors/agents/wholesalers in Phoenix.

Any tips?

Full security deposit for a three month MTR is causing me to lose business and I need an alternative! 

I own the property free and clear and i use the equity as part of my business line of credit.

Can't imagine being in business with characters like this. 

I know the grass is not always greener on the other side, but any tips on finding my next market?

I’ve been in the real estate business for almost three years now and have completed five deals: one buy-and-hold long-term rental, one short-term rental, and three fix-and-flip projects, for which I helped raise capital.

When we purchased our laundromat, it had a strong brand and positive reviews online.

Since it's your current primary, you would need to move out, change your address, and likely get a lease in place before closing on the DSCR loan since the lender needs to prove this is a "business purpose" loan and not a loan on your primary residence. 

My number 1 tip would be to go off market and find owner that wants to sell at a discount / prefers speed and convenience.
