House hacking is an excellent strategy, especially with the potential to use an FHA loan to secure a property with a low down payment. 

Most old houses it is about 4 ft at the perimeter of the room, maybe less. 

You may also want to consider hiring a land use attorney or consultant to help navigate any zoning changes or entitlements needed for your mobile home park.When sourcing land, focus on parcels that are already zoned for multi-family or manufactured housing, or at least close to it, to avoid lengthy approval processes.

What kind of documentation I need to get so I don't lose my capital.A neighbor of mine came with this ask of funding for building houses .

From my experience working with over 400 investors, those who start with house hacking scale much faster.Good luck!

With your focus in using house hacking, Conventional or FHA loans would be your best options.

Hey Brandon,I had good success by getting equity lines on properties to access the cash to invest again. 20% is certainly not essential if you want to go lower there are many lending options for lower down payments, especially if you are willing to house hack!

If you wanted to house hack I would stay where you are at and find one there.

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

The good thing about the houseGood monthly cash flowGood interest rateIf its a headache property, I would sellIf it doesn't have much maintenance and you have good tenants, I would keep it.If you do decide to sell, you have about $200,000 of equity which you can buy 2-4 houses with when the market is more favorable.
