I found this deal listed for sale on LoopNet.

Home went to tax sale county kept excess proceeds.

Would a low enough sales price make all of my concerns go away?

It’s unnecessary and potentially problematic to add the ex-partner to the title before the sale.

when you say "being sold" do you mean the minimum bid amount or the actual sales amount? 

I have the credit, experience and the knowledge on how to underwrite the deal to show their ROI in this arrangement vs a traditional sale. 

Here are the specifics on our Seattle house: 5br 4ba 3,400 sq ft, built in 2019, $1.7M est sale price, $5.5K-$6K/mo est rental value, 4.0% mortgage with $3.3K monthly payment, around $1M in equity. 

of course the sale of hurricane damaged houses also confuses the issue (my house had no such damage but is only about 4 blocks from houses that did). 

Purchase price: $55,000 Cash invested: $25,000 Sale price: $119,000 Bought at around $50kFixed up at around $20kSold at $120k What made you interested in investing in this type of deal?

Unless you are unknowledgable, my bet is you could make more from rent than sale, and still have the benefits of owning the original home while you go do something else.The 25K you have left in property will be netting you(gross) of $350 mo or 4200 per year.
