When I bought my first owner occupied duplex I had to make a lot of compromises.

We compromised at 405k and I closed on time as promised.

If that is her dream area and you can't afford to buy; buying something elsewhere to increase your income...and have a tenant pay down the mortgage on the rental, is a good compromise. 

But the tenant was prone to using spray chlorine & one of those green scrubbing pads to clean the counter tops & the use of a cutting board would have helped prevent compromising the surface.

Then taking care of it.Just to be clear for posterity, the floor isn't meaningfully compromised and the rail has a little give.

I primarily invest in lower end homes as well and the main problem with them is even though they cash flow greatly, your exit strategies are compromised because you can't refi out of them do to the appraised value being so low.

I could have used that equity to purchase another rent home, however I'm married and my counterpart has weight in our decisions, so I had to compromise.  

Things like failing foundation and compromised structural supports.

Seller was unrealistic and unwilling to compromise on price, terms, anything so I walked and I believe it still hasn’t sold. 

Negotiate with the seller by discussing the needed repairs to come to a fair compromise to make the bad deal a fair deal.
