Maybe mobile home parks?

Unlike long-term rentals, STRs can be treated as non-passive, allowing depreciation deductions, including bonus depreciation (40% in 2025) on eligible assets.For tiny homes, tax classification matters:If mobile, it is considered personal property, allowing 100% depreciation under §179, subject to income limits.

If the RV is not permanently affixed and retains mobility, it is considered personal property and depreciated over 5 years under the Modified Accelerated Cost Recovery System (MACRS).

I personally use the mass text capabilities through my Resident RE CRM.However I have a few friends who wholesale and invest and use Mobile Monkey to mass text and from what they say the price is pretty reasonable.

Recently decided, to invest in a mobile home park but sold at a loss.

The mobile home I would only want to keep for a few years to live in before building a new home. 

A client of mine recently renovated a mobile home in Tempe, and it's become a surpisingly lucrative rental.

Have you looked in to being a mobile notary?

Unless the land is super valuable, probably not collateral for the mobile homes.
