He breaks down using Self-Directed IRAs (SDIRAs) to invest in real estate—like rentals or flips—and keep the profits tax-free.

They are requesting to go month to month at the end of the lease term, I am okay with allowing them to do so with a slight increase in the monthly rent (My current lease does have an automatic renewal clause that would be month to month if no termination notice is received by end of the lease term, I just need an addendum to increase the rent amount).

Based on similar deals I’ve worked on, the quotes you’ve received so far seem pretty standard.  

I also received a letter from the county saying that my property is in violation of several health and safety codes. 

I'd recommend searching the forums for topics you're interested in to get a solid base and direction. 

So far, the BnB is well-received in the neighborhood, and a priority is to keep it that way long-term.Thank you in advance! 

Real estate is a long-term play and cash flow is the last benefit you receive.

You would want it to appraise for $200k (assuming they require 20% down + closing costs) so you would then have a $200k loan but have received your $150k back to do it all again. you could also do this with a bridge fix and flip loan as well.

Or should I try to communicate with him directly to pay?

The title company probably requested a payoff and had not received it and then got notified of the lis penden.
