Quote from @Sherry McQuage: Make sure to check the zoning to make sure mobile homes are permitted there; check for any hazardous waste designation for the area; will you need to have the parcels surveyed out in order to sell the size you intend? 

We have a big place so it is families and groups.I do ask guests before booking if they are celebrating any special occasions and I will add some extra things to the welcome box that fits if I can.

If the answer is yes, then it's a no brainer to make minimum payments on your 2.8% interest rate mortgage, and use the funds that you would have paid extra to pay it down faster, to either invest in more real estate, the market, or anywhere else where you can get a ROI > 2.8%.If the answer is no, then feel free to aggressively pay it down as fast as possible, to become debt-free faster, and just have a large amount of money in savings or to splurge with.The bottom line is that your 2.8% mortgage is GOOD debt.

Now, with the ADU rules, developers are buying anything close with some extra space so there may only be scraps left that wouldn't pass FHA or would price you out.

No lending institution or bank would be permitted to operate with those ratios.
