I agree local banks and credit unions will be better if you're planning on growing your portfolio. 

--reach out and thank them upon getting the booking and ask if they have any questions--send a "Welcome" email or automated message during the week prior to arrival--reach out the day after arrival to ask how everything was the first night and ask if there is anything that the property needs--reach out at the end of the stay (that morning or within 24 hours) and ask how everything was, anything to improve, anything to add to the house and then offer an incentive for returning guests.My 2 cents,Mike Absolutely stay in your place as Mike said.You will see things the cleaners will never let you know about.We stayed in our PF will putting up the Christmas decorations and found a cracked plastic shelf in the fridge. 

This would improve the property value and also allow you to lease out the 5th unit.

While it's positive after expenses and has potential for improvement in year two, it’s been a bigger hassle than anticipated and taking attention from other priorities and areas of our life with not enough return. 

Verify credit, employment, etc for you. 6) I would definitely want noise (quiet hours), guests, and treatment of common areas covered. 7) We've used Rent Manager as it focuses more on the financials which I think is super important.

Any good recommendations for the collection agency or any way to get the money back from the tenant or any way to report it to the credit bureau?

If I were in your position, I would look for a bank or credit union that will give you a line of credit against the rental property.

Thanks @Don Konipol, but I can’t take all the credit here.

Basic staging with an agent usually means they give you insight into how you should:Declutter and depersonalize by removing photos and personal itemsArrange your furniture to improve the room’s flow and make it feel biggerAdd plants, move art, or re-arrange other accessoriesFull-service staging is another option if your house needs more hands-on attention.
