Getting more than 1 aspect on 1 property is a bonus. 

Try to hang on until the end of the lease, or at least until there’s only 15-30 days left if the tenant is really keeping the property up and will let people walk the property while they pay rent.

So the barrier to entry is not as high as traditional investments.

UW is very fast. 

Here is something I dug up that might be of interest. 10" Memory foam queen mattress.

I'm not sure why you'd target mobile home parks that's one of the hardest to entitle. if you want a scalable strategy for 10+ years stick to residential horizontal, apartment, etc that is more common for your market. 

The STR is in New Orleans, BTW.

The current property is propane-only, and while natural gas is available, the cost to bring the line is around $40K–$50K.

The amount of this deposit is going to depend on the auction itself.

Ideally, you'd want to have signed leases from each tenant, but the strategy part of it is that you also wanna make sure that you don't run people away while you are either increasing rent or preparing any units that are currently vacant.I would probably take a step-by-step approach.
