It's a major job - which is why you can pay a company 8-12% of monthly rent to do it for you.Again, if there is something I'm missing please advise, but since your wife already owns it it seems like you're in good shape.  

My apartment lease will be up soon so I was advised that the numbers could also work using an FHA to buy a home with a basement/finish basement apartment with an exterior entrance.

The insurance agent advised me that people suing an LLC normally sues the LLC and LLC members personally by default.LLC means you also have LLC fees, and unless you're a single member, additional tax returns on the state and local levels.

To make a strong offer agent advised we offer to pay title insurance cost and $250 option, 1% earnest.

I would typically advise to find a local bank that is convenient as my guess would be most rates will be comparable to point it may not be worth extra hassle. 

Thanks @Andrew B. for your advise! 

As advised to me, I’m planning to buy SFR with ADU potential in the SDSU area and rent to students.

Thank you for the advise.

Excellent advise here.

@Tishon Greene it won't be worth it to pay an appraiser to come and advise because different appraisers value things differently.
