So that when the inevitable happens, you will have a prudent reserve set aside to cover those costs without impacting your cash flow.Lastly, I'd advise setting a further 10% aside for a property manager. 

Then of course there are direct bookings and VRBO/BDC reservations that are processed through Stripe...

There were a few things assumed on this, which make me question how good the numbers look - assumptions being that I could negotiate to a purchase price of $90k and that each unit would get $700/mo for a 1br/1ba.That said, here are the questions that I have (I understand that some of this will come more naturally with better understanding of the local market, but as I build that knowledge, I'd love to see what people here have to say):- Are these assumptions too aggressive?

If you are in a situation where you are holding the apartment until the tenant has the rest of the funds, we use a 'reservation fee' and have the potential tenant sign a reservation fee form.

I've poked around the marketplace but I'd really appreciate a reference to an eastern Kentucky licensed realtor who is internet savy and has the experience to list 277 acres w/a house and barn w/heated conc flr about 10 min from Natural Bridge State Resort Park, Wolfe County, KY.

Property has good reserve and ability to carry itself.

@Bryan Richard Population of the town, loan size, occupancy must be 80%+, quality of the mobile home park and debt service, a credit score above 650+ and have 6 months of reserves is critical. 

You will need reserves as well.. .and this pile should grow with the more rentals you have. 

However, you want to make sure you have a good amount for reserves along with money for other admin fees.

Nature vs other.
