I strongly suggest you review your estimated value.

I especially ask if I see that they've worked at a different institution by reviewing their Linked In profile.  

In our title company reviewing the title there are two junior liens on the property, one from the HUD and one from the HOA which sold their lien rights to an investment company.

When you bought the house and inherited the tenant, did you review his contract with the original landlord?

Do you work with a lender/broker that can review your draft taxes before you file and let you know if you should ease up on some of the deductions? 

Most large servicers have document processors as the initial review to make sure everything is complete, and THEN it goes to approval process.  

Track everything you do (you are responsible for) and review your income and expenses regularly to discuss that to hopefully reduce your expenses and increase your income that will make your business grow.Be careful and consistent on what you do.  

I have nothing but 5 star reviews across like 5 sites.

There is a BRRRR calculator the site has so be sure to educate and review that. 

The usual contract disclaimers apply: don't sign anything you don't understand, have an attorney review it if doubt, etc.
