It will not be sexy, but it can change your life (I've house hacked twice and it's certainly changed mine). 

If the seller isn't responsive, then do like the idea of telling the tenant you tried, and see if they can get some free legal assistance from a tenant resource center.It is a good reminder as closing approaches to ask the seller to keep tenants updated on the pending sale and when ownership is scheduled to change.

There is a lot more state regulations and lending laws change when 5 units or great.

Yeah the law changed I believe back in 2020.You cannot do short term rental with an HPR unless you own both sides.   

One would think a tenant with an ounce of brains would change their habits with the first violation.You need to get rid of this tenant. 

I’m not suggesting a person change their business model entirely, but usually a person either deletes something or adds something in order for a different outcome or at least a more modified outcome.What’s your thoughts?

Paying it down faster doesn't change your payment.I recommend you speak with your lender so they can explain this to you.

@Jaycee Greene as of right now I am not close to anyone in the community but am looking to change that.

I'm interested though in how that changed after the 2008 crash and why isn't it the same if it is truly not.

.: I would go HELOC for sure that would be best as others were saying the lower cost for the money changes between paying a higher rate for a personal line and typically personal lines they want a higher monthly charge as well independent from the interest rate.
