I understand your fear of your units being vacant but if you are in the right location, and you can commit to proving clean, safe, affordable housing, the demand is incredible. 

There is no one size fits all Plan B, but I am a firm believer that paying off a mortgage and getting cash flow on fewer properties in high rental demand areas is a better strategy than having more properties and higher debt in riskier neighborhoods.

I think there are few different ways to do this (e.g: lease option, subject to, land contract) Check out this article to get started then search the individual tactics in the BP search bar to get more info. https://www.biggerpockets.com/renewsblog/2011/07/20/seller-financing-3-kinds/

If you don't mind, I'm going to share with you a step-by-step guide that commercial brokers in NYC like myself would use:1) Check market demands: Before anything, you'd need to find sales and rentals reports for your neighborhood and check the current inventory.

I'm not sure if that's due to liability or lack of demand (as you pointed out, pools have liability and there are lots of them in my market as well).Every time I visit the property, there are 3 or 4 young kids (under 10) playing outside on the grass, and I would really love to have a playground for them.

In my experience with multi-tenant leases for a single unit, one thing we have verified is that each individual tenant could carry the lease themselves if need be financially.

@Kalen Jordan These are good PM questions, but in order to get that data you have to ask it of any individual turnkey team. 

Just trying to gauge market demand here with a poll on seller financed mobiles with land, and see if they work as rentals vs land banking vs ...?

Starting off as a newbie with little or no experience no private lender is going to loan you money unless you know some wealthy individuals or have a good relationship with them.

Suggest you visit all the Title & Escrow companies in your area see what the demand is.
