@Mike Imbriglio the lien is for all intents and purposes going to be added to your purchase price, because it is unlikely the seller has the money to pay it off and you can't get clean title without paying off the lien, (that is what its intention was). 

Apartments are fully furnished, you pay all the bills, in many cases you provide cleaning and transportation services.Turnover is constantYou are managing a community on top of managing a propertyCash flow can be a lot better than compared to a traditional rental

Of course I know it’s there, the inspector wasn’t worried and advised me to clean it with bleach as it was dry, so it must have been from some older, but since fixed water damage from the 2nd floor unit.

This is also the first property where I assembled a small team to help with cleaning, repairs, and snow removal.

We'll freshen up the paint and wax the terrazzo floors, but you're not getting a kitchen, new carpet and the nines. 

What’s your plan for cleaning between guests? 

If there are vacuum lines in the carpet, add $1000.

I inspect my own properties once a year, I try to take care of the things that reduce later damage like cleaning the gutters and servicing the furnaces.
