I've now looked at the first five houses. Interesting.
There was a house from 1890. TONS of character. Also a bad roof and asbestos, which the listing said the seller is going to replace and remove, respectively. Good for him, but I don't want to get stuck with a cheap roof and a shoddy job of asbestos removal,
and it's too far away, so I've removed it from my list.
Two other houses, one dating from 1900 and the other from 1956, have their own issues. Eliminated.
The duplex from 1994 is too small. Gone.
Leaving one near-by house dating from 1960. Looks nice, not too small (1452sqft), in an out of the way location. Asking $150K. Ow.
It comes down to affordability.
