My tenant has been living in the condo for over a year and is out of the hospital and back at the condo.The new outside fire door costs over 3000 USD.  

Please correct me if anything I say about my plan is wrong and I'm willing to learn/listen to more advices here.I'm currently living in PA will be paying off my house this year (only $20,000 left).

.), the same day I receive a message from her boyfriend (I think) who I met once briefly but does not live at the property, saying that she is not living there, and that she cant be reached.

The only issue we did have was unwanted people living there who were not on the lease.I am not sure on the specifics in your state as to evicting these people in case that you need to. 

Especially if the nails/holes in the walls were no bigger than lets say a dime, it would consider it standard wear and tear with a tenant living there for 2 years. 

Since currently we are saving money by living with my parents, I would be hoping to use my first purchase as a place we could also live in.

What he wants to do here is more of a co-living situation where you are renting out all of the rooms inside the property.

I appreciate any feedback/assistance.I have been living in Paraguay for almost 3 years and now I am looking to start a RE Investment Fund to capitalize on this growing market, seriously :) I plan on bringing in accredited foreign investors mostly from the U.S.

She's offering thus at no points but credit is 800 and it's an investment with tenants currently living in both units 

We live in one unit on our duplex consisting of two stand-alone houses in Ventura, California.
