I'd encourage you to reach out to more experienced investors in your area!

Cash for keys is probably going to be the cheapest because I'm sure California fines won't be cheap and neither will attorney fees.Once you get her out I strongly encourage your dad to get the building legal…although not really sure what that means in this case but would want to go down the same road again.  

I encourage you to get comfortable with the notion of taking the leap. 

Thank you for the encouragement.

Among other considerations, I've strongly encouraged my father to keep a significant cash reserve and to apply for a HELOC – to be kept as an emergency line of credit, not used, of course.

But if your neighborhood will support that size house, and it fits with your philosophy of offering good homes in the lower strata, I applaud you - most communities have a dire need for affordable housing. 

I am hoping the people here will be able to give me a little knowledge and encouragement.

@Luka Milicevic I would encourage you to keep trying.  

Is there a way to encourage cooperation from the bank?

How did you impose your rules or philosophies with the tenants?
