(Once I had a tenant claim mold was in the oven, I went over there...was just residue from where my folks cleaned it).2) Have tenants hire a professional.

Also, the concrete underneath probably needs treated ahead of time with a bonding adhesive. 

Not only are you providing cash to the owner, but you are managing the property and creating residual income.

And at the end of the day there is very little residual or referral business  .. 

I visited my first hoarder house today that reeked of rodents, mold, and fumigation residue.

I will say, with furnished rentals, it takes time and money to fully furnish them with all the bells and whistles but it did allow me to get higher rents... only downside is, if you are out of state, it is not easy to manage remote unless you have a good property manager/company.I have personally started to transition out of STRs due to zoning/town regulations and have already unfurnished one of the apartments to turn it into a long rental for more stable residual income.

Instead of the snap it has an adhesive.

As an investor, the goal is to generate consistent residual income.

Once the deal was complete, I used delayed financing to pay back the first 80% percent and created a second loan with my family to pay back the residual.

I all fairness to you to have placed my auto draft for my rent on hold until I get information about possible residual health problems.
