If it is mold, is the toxic variety.   

To start with trying to get the tenants our, your first mistake was hiring an attorney that probably intimidated them and you caused them to build a wall that reduced your ability to communicate in any compassionate manner when you know they are elderly and have a family member they care for.COVID has caused everyone on this planet a huge amount of stress and now you want to add more stress by upending your tenants' lives.

You can find the best deal on the planet, but if you have lousy property management, it can be like flushing your money down the drain.

Because if this company has owned it for 16 years they've got to be the worst wholesaler on the planet :)It could be that the new owner of the property wasn't properly recorded.

The rest of the planet does.Let me close this debate with saying this... the inherent disconnect here is, that you are STILL trying to defend your points with the erroneous understanding you have of SEO.

I tell everyone I know: if you call someone up for a job that costs less than a couple hundred bucks in materials and isn't some crazy oddball thing - patching damaged drywall from a leak is not an oddball thing; fixing a partially collapsed porch might be - and the guy can't give you a ballpark figure over the phone and says they have to come "see the job", they're going to try to milk you for every dime on the planet - because truly busy contractors that do lots of work know roundabout how long various jobs take, how much they charge for their labor, and about what the materials cost.

Having 2 cars and a smart TV does not make our life or the planet's better, it makes it all that much worse.
