I am bad at this forum writing but will try the best I can.This all takes place in crazy Brooklyn.Roughly 2 years ago we were living in a 1 bedroom apartment 500 SQF with 2 kids we were paying $1200 monthly rent. one day the landlord approaches me that he needs the apartment for himself he would like to build up another floor and make himself a duplex and we need to move.I had no money saved up no way to buy a house so I I was going to drag it out with my landlord as long as I can (Any other apartment in my neighborhood would cost me at least $2500).After 7 months my wife started making me crazy to move we just ran out of breathing room in our tiny house.Long story short I told my landlord that he will have to lend me a substantial amount towards my down payment if he wants me to move, and he agreed so now I had what to work with. 

Some older parks are laid out so tight with short lots you can't buy a home to fit the lots today and new zoning requires set backs further shortening the replacement home.Some parks are simply dead or near dead because they are full of ancient 10'x40' or 50' homes and the lots are so small you can't buy a replacement home for those tiny homes.

We are both successful small (tiny) business men working as consultants in mechanical industries.

Ours is not the same situation as yours, but we did purchase a Pioneer mini-split system for our 144 sq. ft. tiny house.  

When you take a look at the foundation look for major cracks to make sure you don't have issues there.

I think @Brice Hall is Jaded cuz you cant buy $30K houses in New Your unless they are in F Neighborhoods the world is a big place, and markets are very different if you leave the tiny world of you back yard. 

I've actually had people approach me to see if they can leave their Tiny Homes on the lot for monthly rents.Thoughts?

You all crack me up!

If the State or the City aren't cracking down on your VRs, the HOAs will gladly take on that job.

Tumbleweed Tiny Homes are popular in California.
