@Elijah Crew100% financing is a tough one to find. 

The IRS doesn't need to prove you are lying, you need to prove that you are telling the truth. 

I completely redid and finished the basement unit of my rental by myself over a few months as well, its tough work but well worth it in the end!

The challenge you might be facing is financing especially with smaller parks (under $500k), very few local banks offer financing for them, and if they do, they want you to have experience or at least prove that you know what you're doing.

It will be tough to get away with using no money.

With the market the way it is, finding profitable investment properties can be tough.

All adds up that a pool is tough (maybe impossible) to obtain additional rent on long term rentals that covers the maintenance/cap expense.However, cost to add a pool is very large.  

I have signed leases and have years worth of bank statements to prove that I'm bringing in the rents (which I'm also claiming on my tax returns).

@Paul Riley Tough question because you really need both for success in REI. 

Finding deals is tough in those markets unless you're prepared to go off market.
