I'd say the biggest landmine to watch out for is our property taxes.

With the down payment you're putting down (assuming it's at best 25%) with current interest rates, you're maybe going to be scraping a couple of backs cash flow on a Class C+ property. 

I mean one of these posters was told their "turnkey" property had dangerous sidewalk conditions questioning how "turnkey" the property was and their response was the tenant's don't care about the sidewalks.

Unfortunately, my experience has also been they Sec 8 tenants have generally been rougher on property. 

I am learning a lot about real estate and want to purchase a rental property in my area.

My neighbor did STR on 2 properties in Long Beach, but only allowed 30+ day rentals so that he did not have to register with the city.

That said, you will need to make sure the property meets the definition of rural first.

Can I ask how many properties you have and how long it’s taking you?

The land is tangible and the mobile homes are considered Personal Property and titled like a automobile.

Would you suggest subdividing the property, building a single house, or building multiple cottages/ tiny homes?
