The issue I'm discovering now is that, when I go to apply for a mortgage once I have completed this live in Reno, my debt to income ration will be too high.The solution I was planning to do is to add myself to the title of her home as joint tenancy and rent it out, at which point, I could claim 75% of the rental income towards offsetting my debt to income ratio, which would likely qualify me to obtain another home loan for another personal residence for my family to call our actual home.Does this seem like a sound solution or am I missing something?

To rational people it seems like these would be highly motivated sellers but they arent.

However, I'm not sure how the pro-ration works with a duplex. 

And, you have to be very strategic with the ration of time you spend there versus rental time so as not to send up red flags for the IRS.

And they may rationalize that if you have the money to sue then you have the money to pay.

Don't rationalize anything that falls outside of the above criteria as valid. 

If there's not enough volume to justify your own dedicated dumpster, or no physical space for the dumpster, it's a possible solution.I don't know if it's compliant with the letter of the law, but for these sorts of things I act rationally and create a paper trail to document effort ... and leave it up to someone else to object.

I was going to forego sewer scope - I’ve been rationalizing that this is fine since it’s 1980s built, however really I’m deterred by cost.

EtcThere are upper, rational fears and lower, 'survival' fears. 

What matters is you don't get so wrapped up (frustrated) if it seems like it's taking too long, and accept a bad deal...then rationalize it to be a good one.Just focus on the deal...and not the time.
