What an Appraisal Really Does (and Doesn't Do)

If your York County rental is being bought by someone using a mortgage, an appraisal is part of the deal. The lender orders it, a licensed appraiser inspects the property and the comparable sales, and the result is an opinion of value the lender uses to size the loan. For a lot of sellers, the appraisal is a black box that occasionally derails a deal. It's worth understanding what it actually does — and what it doesn't.
What an appraisal is
An appraisal is a documented, defensible opinion of value prepared by a licensed appraiser for the lender. The lender won't loan more than the property is worth, so the appraisal protects the lender's collateral. On a 2-4 unit, the appraiser typically uses two approaches:
The sales comparison approach — recent sales of similar properties nearby, adjusted for differences in size, condition, and features.
The income approach — what the property's rent supports as value, used more heavily on income property than on a single-family home.
The appraiser weighs these, reconciles them, and lands on a number.
What an appraisal does not do
It doesn't set the market price. The market price is what a willing buyer and willing seller agree to. The appraisal is one professional's supported estimate, ordered for the lender's purposes. A property can sell above or below an appraisal in a real transaction.
It doesn't inspect like a home inspection. An appraiser notes obvious condition issues, but they're not crawling the attic or testing the furnace. The buyer's inspection does that. Don't expect the appraisal to surface deferred maintenance the way an inspection will.
It doesn't capture everything a local buyer values. Appraisers work from comparable sales and standardized adjustments. A specific feature — a rare off-street parking setup, a strong long-term tenant, a location a local investor knows is appreciating — may not show up in the comp math even when a real buyer would pay for it.
Why the comp set matters so much
The single biggest driver of an appraisal number on a York County 2-4 unit is which comparable sales the appraiser chooses. Small multifamily sales are less frequent than single-family sales, so the appraiser sometimes has to reach — older sales, properties in a different borough, single-family comps adjusted to a 2-unit. A thin or mismatched comp set is the most common reason an appraisal comes in low.
This is why an out-of-area appraiser can produce a weaker number than a local one: they don't know that a sale three blocks over isn't really comparable, or that two boroughs that look similar on a map are different rental markets.
When an appraisal comes in low
If the appraisal lands below the agreed price on a financed deal, the buyer's loan is sized to the lower number, and the parties have to decide: the buyer brings more cash, the seller lowers the price, they split the difference, or the deal falls apart. It's one of the most common reasons a deal cracks between agreement and closing.
A low appraisal can be challenged — it's called a reconsideration of value. The path is to give the lender better comparable sales the appraiser missed, or to point out factual errors in the report (wrong square footage, wrong unit count, a comp that wasn't actually comparable). It doesn't always work, but a documented, specific challenge succeeds more often than a complaint.
What it means for a seller
Three takeaways for a York County 2-4 unit owner:
1. A cash buyer skips the appraisal entirely — there's no lender requiring one. That's part of why a financed deal and a direct purchase run differently.
2. Clean documentation helps the number. An appraiser who can see accurate rent rolls, leases, and a clear unit count produces a better-supported value than one working from guesses.
3. A low appraisal isn't always the last word. If it's built on the wrong comps, it can be challenged with better data.
A direct option in York County
I'm Ed Lane, a local buyer in York County actively buying 2-4 unit rental properties directly from owners. I underwrite a property on its actual rents and condition, and because I know the local small-multifamily market, I'm not relying on a thin comp set to understand what a building is worth. That tends to make for a more predictable path to closing than a financed deal riding on an out-of-area appraisal.
