The ducts/vents of the house were cleaned not to long ago and the tenant wont let the PM have more testing done or mitigation. 

Perhaps they should also run your prints and dna test to make sure the background check didn't miss anything.

If these tenants passed your initial test for being good tenants, you should get them on annual leases.

I understand this eliminates the "self sufficiency" test that the FHA requires for 3-4 units - which is great news. 

As well as a couple that did not pass the sniff test.

There was a tenant in place when I purchased the property so I have not been able to test the PMs ability to market for and find tenants yet.

In one of my properties, a tenant is alleging a child tested for lead exposure.  

I have been a local home inspector for over 5 years(950 + Inspections) but getting ready to test my hand at Real Estate investing.

My team and I have been testing a few options since January and the favorite by far has been Monarch Money.  

And even though virtually every sponsor agreement allows me to share investment information with others who might be advising me on it (especially when club members are bound by an NDA), I still ask the sponsor if I can share it, because it's a test.
