Which is not easy for possible for many people (like your husband).Once you really know what to do, the risk level drastically reduces.

People might be taking advantage of the rising prices.

I provide houses for people that might not get other opportunities.

I'm hoping things move a little more quickly once things go vertical as I heard getting slab poured is the longest wait but I'm assuming there is a labor/material shortage in general in the area so wasn't sure of people's timelines once slab has been poured?

Lots of people who have trailers don't own the property they are on and sell them.As for the owner of the land expecting tenants to do repairs-there shouldn't be many repairs required to the land, just the trailer that is on it (which your grandmother owns and should be responsible for maintaining). 

I warn people over and over and over to know what they are buying and to go personally see what they are buying. 

Think about where those people hang out and network. 

My preference is to prioritize longer bookings and STR in the gaps.

You must work at least 750 hours per year in a qualified RE business.So most people who have high-earning W-2 jobs outside of real estate won't qualify.But the unique thing about RE pro status is that even if you don’t qualify but your spouse does, you can both file jointly and claim the losses from your RE investments to offset your other active income together.It's an incredibly powerful benefit if you do meet the criteria.

The loft is very successful on Airbnb and people love the main house for long term rental.
