It is also not surprising that typical residential lenders would stay away from this type of property as well due to the commercial use aspect.

@Dax Gurr For the most part, I would recommend staying out of the inner city, certainly the low end sections of it.

The large corps / institutional investors behind those buildings don't have flexibility on price due to their construction costs,   while anybody who has held a building for even 5 years around here can if necessary reduce rents a bit to keep things occupied if necessary and stay in the black.  

I don't know if i should stay away from these and look for 1980 and newer to hedge the risk.  

After several months of her living there  I start to see that she has a guy staying with her. 

Seniors are choosing to stay at home, keeping those properties out of the supply chain.If we then ask the question, what is the quality of the population that leaves and the population that is staying and growing?

There is a wealth of knowledge to be gained and connections to be made on the BP forums stay engage and continue learning.

The pre-existing tenant is a great perk, but it doesn't guarantee that they'll stay, and the lower down the prop class ladder you go, the higher turnover you're likely to see.

Maintenance, Taxes, Insurance will never stay the same.

If one tenant requests to move out then have the one staying requalify and sign a new lease.
