Three over-the-counter certificates, $2,410 in, redeemed at the full rate in month seven
Not a big deal and I'm posting it because the small version worked and I want to know what I got lucky on.
I didn't go to an auction. The county keeps a list of certificates that nobody bid on at the sale, and in my state those can be bought over the counter at the statutory rate with no bidding down. That's the whole reason I did it this way. I didn't trust myself in a live auction and I wanted to see the mechanics once with real money.
List had 61 leftovers. I threw out everything with no structure, everything where the tax bill was under $400 because the fees eat it, and everything I couldn't find a clean parcel outline for on the county GIS. That got me to nine. Then I looked at every one of the nine on street view and the assessor's card. Four of them were vacant lots that the assessor had valued like buildable lots but the GIS showed as drainage strips behind houses, maybe 18 feet wide. One was a house that had burned, you could see the tarp.
Bought three. $2,410 total including $30 in issuance fees. All three were older houses in a working neighborhood, taxes between $600 and $950, owners of record for 12 years or more.
All three redeemed. Two at month five, one at month seven. Interest came to $118 on the statutory rate. So call it $88 net after fees over roughly six months on $2,380. Not a business. It's about what a savings account would have done and I don't want to pretend otherwise.
The part that nearly broke it: one of the three had a code enforcement case open that I found on the city's portal a week after I bought. I don't know what would have happened to that if the owner hadn't redeemed, and I hadn't checked the portal before buying because I didn't know it existed.
What I'd keep: the GIS step. It killed four of nine and it took eleven minutes each.
