62 letters, 9 calls back, two sets of financials. $58 in stamps.
The county parcel viewer in the two rural counties I'm working lists 41 properties with a land use code for manufactured home community. I figured that was my whole universe. It wasn't. Nine of them are single homes on their own lot that got coded wrong, and four are one park that got split across four parcels, so the real number in those counties is 27 parks.
That took me a full weekend to work out, mostly by flipping between the aerial photo and the assessor card and counting driveways. Then I pulled mailing addresses from the tax roll, wrote one page in plain language saying who I am and that I'd like to talk if they ever think about selling, and mailed 62 letters (some parks had two or three owner names on file, so I wrote all of them).
Nine people called or wrote back. Six said never. One wanted to talk about his knees and the price of gravel for forty minutes, which I'd do again. Two sent me actual numbers. One is 22 lots, all tenant-owned homes, lot rent $265, on city water and sewer with individual meters already in the tenants' names. The other is 38 lots with 14 park-owned homes and one master water meter, and the seller's expense number is 21 percent, which I now know is not a real number.
Total cost, $58 in postage and stamps plus $11 in printing. The part that almost sank it was trusting the land use code. If I'd mailed only the 41 addresses on the first pass I'd have missed six real parks and wasted a third of the postage on houses.
What I'll keep: counting driveways on the aerial before I believe the parcel data, and writing to every name on the card.
