One of the units will be our primary residence until the new house is ready.I’ve started speaking with our realtor and have done my own browsing and it seems like multi unit homes are hard to come by so it will likely be tough to find a good prospect where the numbers make sense, but we’ll be prepared to jump if we find a good fit. 

I was able to speak with a building owner last week and have submitted the property as my subject.

The property manager says the tenant continuously avoids him and will only speak with him when the tenant is asking to speak with me, the new homeowner (not sure if it is a good idea to speak with the tenant directly or not).

Thank you all for your advice and I look forward to speaking with y'all. 

Generally speaking, and without know the numbers, I would prefer the 30 year fixed. 

These all speak to positive momentum and can prove to have staying power and a longer opportunity runway. 

I'll have to speak to my bank if they will allow that.

If that is the case, you may want to speak with a CPA about filing an amended return with only a single Schedule C for all your endeavors. 

Did not think of that. )Re-cap questions:(1) is it OK (acceptable), legally speaking, to send a notice letter to my tenants informing them of non-renewal when their lease is up?

Generally speaking if they are all CA SFRs, rented and/or all income is fine, credit is good, and looking to go conventional, your rate should be in the low to mid-3's depending, even for cash out w/probably a pt or 2, depending on how the loan is structured.
