How long should we keep our insurance property (if we can even do so) in case the tenant decides to sue us?

We are STR property managers here in Orlando.

We are still involved in the business, but way way less. 

S&P has lifetime return of ~10% and a recent long term return of ~12%.  

After 2 Duplexes ($80,000), we left with $320,000 so we want to buy another 2 Duplexes (same price) with 25% down payment ($112,500/each) since we are not living there for long-term rental which left us with $95,000 left.

You get your money without the tax hit at the moment and hopefully continue to profit off them,   If the objective is long term passive income, it doesn’t make sense to sell them… it moves you away from your goal post.  

Of course, if you think Florida is barely at the beginning of its correction, and has a long way to fall, then I get it.

Hi Tim,There are several effective strategies and resources you can use to stay informed about future development planning in your area, without solely relying on attending city council meetings:City Planning Websites: Most cities have planning department websites where they publish upcoming development projects, zoning changes, and long-term planning documents.

How long has each tenant been in place for?

If you're open to short-term rentals, that could be one option.If you're looking more at long-term renters, you (or your realtor) can negotiate seller credits into the offer and use those credits to buy down your rate.
