Many other investors have asked themselves (and others this question) but what I believe it ultimately comes down to is what are your goals (how much money you'd like to make), are you physically able to manage it yourself and do you have the right organization and systems in place to do it on your own. 

Quote from @Jaycee Greene: Assuming you pay asking price, I'd estimate the down payment for something like that using a hard money loan (HML) would be around 40% of the purchase price and your monthly payment would be $2,600 with an interest rate in the low 7% range (probably need a 700+ credit score to get that).

They could include things like waivers for documents and appraisals, relaxation of underwriting standards and money to fund repairs.However, there are benefits for people who just live in the areas, but aren't directly impacted.

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. 

Maybe they don't need the money now but in 5 years they wan to send a grand child to college.

They never charged money, they loved people that love to learn and hustle. 

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 personally spend about 50K a year in masterminds and always get my money back just through network of individuals you get access to.

Would it make more sense to move the money we make from selling to a different property that could potentially increase our cash flow? 

As long as you don't lose money.
