You have gotten good advice on this thread on how to handle this.

Hi Skyler I’m an adjuster for an insurance company and handle homeowners claims.

If your credit has improved, you may get better terms than you currently have and, even though you may not pull equity out, you can reduce your monthly payment = increase in month cash flow. 

A few thoughts in the back of my mind:Estoppel agreement - need this anyway, but in this case I could clarify any special handshake deals with the last owner and this resident manager.Relieve couple of any management duties like leases, walk-throughs, etc. as I can handle that now.At lease-renewal, make lawn care specifically part of this tenant's lease (and mark rent appropriately lower).Please let me know if I'm close to the mark or far off :)

If the Seller agrees to reduce the price to $210k, this will be a short sale and the bank may have a say or two about it. 

We're having a hell of a time here trying to figure out how to handle STRs.

The areas south and also east of the Intel campus offer great areas with low crime, good schools, shopping, restaurants and newer homes.The newer homes will reduce your need to do major improvements for years on many of the properties.As a Broker and a Property Manager, we see many doing just what you are requesting and having long-term success.

You need to have systems in place to handle it well and make it a smooth routine.

Then u could reduce your work hours since you will hopefully have cash flow from the duplex.

We pointed out that we already offered more than they originally asked for, contract stated they were responsible for providing all utilities through settlement, and they understood they were responsible but weren't going to handle it, but they allowed me to have repairs done before closing and have the contractor paid from their funds from settlement.
