So by spending $42k I collected an additional $75k over 5 years, and then sold the furniture through a consignment store collecting $8k as my share.  

Additionally, you can still find deals that will cash flow and hit the 1% rule and amazing appreciation potential. 

This can put a significant strain on your finances and cash flowThey also often require a large down payment themselves and may have a strict repayment schedule that can be difficult to meet, especially if there are unforeseen circumstances or delays in renting the property or generating income from itIn addition, relying on this type of loan may expose you to higher financial stress and the possibility of default if you are unable to meet your loan obligationsThe final decision depends on your overall financial situation, risk tolerance, and your ability to manage the associated costs and obligations

Also if the whole property or the yard is fenced then an additional barrier fence around the pool itself isn’t required.

I’d appreciate any additional suggestions you might have! 

Additionally, Fannie Mae and Freddie Mac will sometimes temporarily suspend the income cap on their HomeReady and HomePossible programs, which allow purchases with 3% down.

You can later transfer the property to the LLC, but be aware it might trigger due-on-sale clauses or additional costs.

Making additional payments or taking a shorter term are just depositing more into that savings account (it's not like the property appreciates more by paying down the loan). 

An umbrella policy for additional liability. 

Additionally you can do a cost segregation study and get a lot of depreciation benefits to offset the rental income (and potentially other income).
