If the property were owner-occupied, would I only receive credit for one rental unit's income, while the non-conforming basement income wouldn't count?

However, you can claim a tax credit on your California return for taxes paid to Oregon, mitigating double taxation.If you only plan to own this one property, consider using umbrella insurance as an alternative to an LLC.

Not reported on credit.

If it is a credit/equity line, you could provide a lender letter that the funds are available immediately for funding - and cured any recission period. 

If you're using traditional financing on your primary residence, they're going to do another credit check on you just before closing.

Avoid PMI and then go to a local credit union and get a heloc after closing to gift the money back.Have this as a tool in your tool belt but pursue use of the 3.5% FHA, knowing that you will be at a competitive disadvantage if you are competing with non FHA buyers, then you can call in the favor from your gift person.Just know that if someone gifts you down payment money, your bank will require them to sign a letter stating that it is in fact a gift that doesn’t need to be paid back.

I don't take a credit score as a reliable metric in my market.

am working with them now and had the first policy (with Spinnaker) cancelled for nonpayment/late payment so we rewrote another policy (with Millenial) and having the same payment problem again but at least they are communicating that cancellation is coming. they want me to pay by credit card over the phone so the payment wont be late and cancelled again. but when i go to mycoverageinfo.com to check on status it shows its been paid.

Current rate is 5.75 and credit scores are around 750.

You would want to look for an owner that has a loan through a bank or credit union or one that has no mortgage.
