However I am wondering what I need to have in addition to cover repairs and others things that I may not be considering.Any advice and recommendations would be much appreciated!

We recommend you get management contracts from several PMCs and compare the services they cover and, more importantly, what they each DO NOT cover.

I'm making a healthy downpayment cash by doing a cash out refinance on three of my established properties that I know can cover the debt service handily.

A DSCR loan could definitely work, especially if the park’s cash flow can cover the debt.

This is after covering all expenses and setting aside a certain amount for reserves to cover future expenses like capex or vacancy. 

For example do you have a great w2 and can you afford to cover costs of a major repair or 3 months of vacancy?

However, before you do so you should ensure that your revenue from rental income covers ALL your property expenses in the townhome, including mortgage, taxes, insurance, maintenance/repairs, vacancy, property management, etc...

Video walkthroughs, uploads of weekly pictures and videos each week.

I hope you have a lot of cash available to cover the FTC fines. 

Insurance would cover it, I would pay the deductible, and no assets would be lost.If you are in an area like San Diego where people are more likely to sue, a judge is more likely to find you guilty, and the payout is expected to be higher, you may consider an umbrella insurance policy.
