As a local manager we don't come across true squatters very often. 

Is this true? 

I'm not sure I fully understand what FDIC insurance covers, but want to make sure our money is protected from any fraud or cyber incidents while we shop for another house.

It's true that you can do a longer contract and most wholesalers do but also most wholesalers fudge the numbers and make the ARV much higher than what it's actually worth or the rehab cost is way too low.

The tried and true way is to purchase a off-market property, rehab for no more than 75% ARV, refinance to get your money out or payback the private hard money loan - start short-term leasing the property.

You might do some value-add type rehab, raise rents, reduce expenses by upgrading systems, appealing assessments, shopping insurances, etc.If you can find a deal now and you work that deal, it should on average get better over time ESPECIALLY when you get that opportunity to refinance at a lower rate.

Can you elaborate more on what you mean by "Commercial" - are you looking for a business-purpose loan on a residential investment property or are you looking at true commercial real estate (office, retail, etc)?

I'm trying to keep costs low while providing value and so I'm doing some shopping around.  

basically if its TRUE RV there needs to be on site manager to collect payment when they roll in for the night and most RV parks also have amenities that need tending

So many different little neighborhoods of residential that surround bars and restaurants and shops.
