Greetings.
if you look a bit farther south- 78745, you'll see a growing trend in this tight market in which duplexes are being converted to 2 unit condo regimes. I think another one popped up in my feed this morning as sold- Dowling Cove. Another recent one on Matthews lane, one pending on Woodhue.
I think there is something of a sweet spot right now in which the seller is getting a higher return by selling the individual units, but the buyer of a single unit is getting a much more friendly price than anything else in the neighborhood, still below the 350 you mentioned, and lower condo fees than you mentioned, and without the hard to wash off, grimy feeling the wholesaler leaves you with. I think that sweet spot may be less sweet to the buyer in 6 months to a year.
Appreciation in '45 has been great and if you were going to owner occupy for a few years then rent, it might be a good play. I'm sure many are willing to pay the premium price for SOCO or SOLA north of Ben White, but my wife and I been fortunate in the '45.
