I am hoping to roll these two into one loan and reduce my monthly payment/ interest rate on the HELOC as I will be having the debt long term.I also currently own a 11 spot RV Park which I own all 11 units and is currently generating $10,375/month in rent.

Conventional loans that use your debt to income / DTI to structure the loan require 12 months seasoning to use the new appraised value for a cash out refinance.

Get it under contract, ask for all the leasing leads, why hasn't this seller signed anyone?

To do delayed financing or a cash out, you can go conventional where you use your debt to income / DTI ratio to finance or you can do a DSCR loan if an investment property.

This is what usually leads to threats of legal action by the tenant. 

The terms on the debt look good.

This also leads owners to ASSUME simpler is better when it comes to management contracts.

My first rental has over 100k equity and the rent is almost double the debt payment (I've got a really great mortgage from 2020 so it cashflows very well).

This could lead to a huge tax bill and penalties at the end of the year. 

Federal debt and fear of hyper inflation has homeowners in a gridlock.
