This vary heavily town to town. 20% down is great if buying strictly as investment but if you have a way of owner occupying I would explore that route and apply the 20% down to increasing value of property and instead using low money down loan. 

You can also hold money for maintenance, capex, taxes, insurance, or other projected expenses.

Quote from @Daron Williams: I just invested in a tax deed here in texas it was a beautiful lot right on lake sam rayburn. i have it on the market for sale the only problem is you have to have two lots to build on.. i found the person that owns the lot to the right of me and there willing to possibly sale there lot the only problem is i dont have the money or the credit  to purchase it.

Best of luck to all you out there.How much did you pay for these 3 buildings initially and how many years did it take you to earn the money to pay for them?  

My park is in Oklahoma, and I am wanting to start with metering the water individually any advice about best metering equipment for the money would be appreciated. 

I'll do this before my tenants move out however, my intention for this is so they can get the most of their money back.

If I were you, I'd pass on this property and look for something else (and I suggest a 3 BR) under $80 that you can put a little rehab into, unless insurance pays your family member a bunch of money and they accept a much lower price. 

Belly to Belly is the best way for private money..

It cost us more money than we would have liked to have spent, but we were able to put a house on the market that we were proud of.

Just make sure you are saving towards those slow months during the peak months, buy a deal at the right price (don't overpay just because its a turnkey STR or you think it will make more money than projected), and look into ways to increase bookings during those slow months with some marketing and operation tweaks.
