There are definitely some hiccups with it being a small company, but I do have to say that their response time on tickets is really fast.  

Does anyone hear have any experience with either of these companies? 

My company is Flex Property Management & Consulting. 

Companies typically last only ten years on average.

The property is only 9 years old so that's why I put only $10k also, they are opening a new company that will employ thousands of people nearby so that's why I put a 6% income growth and only 3% expense.

Quote from @Trent Reeve: well, a company would have to 50 states and build in integration functionality for 50 different systems.

We learn to build relationships with people and companies.

and frankly most landlords send a technician to fix things, not go there themselves, same goes for lawn care, usually you have a company that comes every week/other week, you do not need to be there.... 

It comes down to how each county handles property tax valuation.To put it in generic terms - a title company & lender will base your initial mortgage payment on the property taxes of the previous owner.  

It is not legitimate and I do not legally owe this balance, but have been unable to get it removed from my history unless I file suit against the company.
