I mean one of these posters was told their "turnkey" property had dangerous sidewalk conditions questioning how "turnkey" the property was and their response was the tenant's don't care about the sidewalks.

Held for 1 year, completed updates, the property appraised enough to justify sale.

If they over-promise and under-deliver, transfer the next property to a different PM.

I just checked all my properties and they are still showing up in chronological order.

The property had foundation work done just prior to the sale but continued having problems, even after I hired a second contractor to correct.

My goal for this deal is to purchase a cash-flowing multi family property to buy and hold.

Since acquiring a four-unit property on the Northwest side, my bi-monthly bill has typically been around $500.

Where is the property located.assuming the seller added the ADU and did not disclose the ADU in disclosure forms, you may have recourse (depending on the rules of your jurisdiction) but it may cost you some legal fees. 

We each pay $300/month (allegedly) and there is zero upkeep to the property (no pool, landscaping, common area).

I use Avail software and it will list your property on 10+ websites.
