Whether an appraisal license is a real second income in a four county rural area is worth working out with numbers.

Three hundred files a year at two inspections a day means inspecting three days a week every week and writing the other two, with no vacation and no sick days. I would cut that to 190 or 200 for a first full year while you are slow at the report, which puts you nearer 85 to 90k gross. Then take out the vehicle. Rural appraising at 45 minutes each way is 25,000 miles a year easy, and at real cost that is a meaningful line rather than a rounding error. Still might be worth it. It just is not 135.

The supervisor wall is the part I'd solve before spending a dollar on education. I looked at this route too and every person I talked to said the same thing, the hours are the choke point and supervisors have little incentive to train someone who becomes their competitor 20 miles away.

Did you ask him why he said no to the other two? If it's liability on signing off, that's one conversation. If it's competition, that's a different one, and at 63 he might respond to a succession framing rather than a training one.

@bmoreno23's succession point is the actual deal here. He's 63 and covering three counties at four week turn times, which means he's turning work away. Offer to buy the practice on a five year note with you as the trainee from day one. He gets a wind-down and a buyer, you get the supervisor and the client panel. That's a lawyer conversation once he says maybe, since the supervision requirement and any purchase terms have to line up with your state board's rules.

I've hit a ceiling on my own deal count for a version of the same reason, capacity attached to one person doesn't scale, so I'd be careful about buying into that shape without a plan for a second appraiser eventually.

The volume assumption is the one I'd stress. Your 300 files rests on transaction and refi activity in three thin counties, and appraisal demand tracks both directly. Automated models are already taking a large share of home equity work and that share is projected to keep climbing through 2026, so the routine low-risk end of your future order book is contested before you've written a report.

What's not contested is purchase mortgage work and anything odd. Acreage, mixed use, outbuildings, manufactured housing on permanent foundations, properties where the model has nothing to lean on. In a county with 90 to 120 arms-length sales a year, a very large fraction of the housing stock is odd by that definition, which is a decent argument for your market specifically. I'd want to see the county's annual sale count for the last eight years before I committed two unpaid years.

One more cost nobody has named. Data. In a low sale count area you will be paying for MLS access plus whatever public record product covers the counties you are not a member in, and if any of those counties sit in a state where sale prices are not public you will be confirming prices by phone, one broker at a time. That is unbilled hours on every file. Also, @luis_carrera is right about the writing bottleneck, and it goes the other way after 18 months. With anything form driven, the first hundred files take roughly three times as long as the second hundred. Your 200 file first year could be 280 in year three. Whether that arrives before the 63 year old retires is the timing question you are actually facing.
