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.

Your monthly payment will be $18,401.36.

Fine a seller financing deal 10% down interest only payments for 10 years 4% I/O with option to extend until a ballon payment.

I used the equity in my previous vacation home for the down payment.

Especially if you are going to house hack, if you earn $50k salary on a W2, you can likely buy about a $200k house (yes you need savings for down payment, so that ramen life, keeping the college, paid off car, and living at home, if possible, or with as many roommates as you can find will all help).  

It’s bad if you can’t afford the loss and whatever payment obligations you have. 

The higher you go in price, the ratios get too hard to make it work without leaving as much money in the deal as you would a standard down payment.

Try not to have your PI payments exceed 50% so assuming 50% expenses and short and long term cap x you might be safe.

However, I just received a text alert that I must agree to their new Terms of Service by 10/7/24 to continue processing payments. 

@Muhammad Kashif to avoid interest related transactions:1) Buy & hold rentals - you make your money back via rental payments.2) Funding flip deals - instead of lending at an interest rate, you could lend for a percentage of the profits on the sale.
