Dental Office Feasibility Study in the Santa Rosa-Petaluma, CA Metro Area

What SBA's own loan files show about dental office lending in the Santa Rosa-Petaluma, CA Metro Area, and what a feasibility study for a project there has to test.

Dental practices as a leading class around Sonoma County

Dental offices take fourth place, 4 of 39, in the class order of the Santa Rosa-Petaluma, CA Metro Area, and the area sits 47 of 562 for dental loans across metro and micro areas. A 2.18x location quotient signals that dentistry takes more than twice its national weight of the local loan book. The median loan of $548,500 is 1.08x the nationwide median, so tickets are close to ordinary even though the concentration is not. In total, 34 approvals between FY2017 and FY2026 add up to $26.0 million, all in Sonoma County.

Program use, yearly counts and two holders

A band from $403,025 up to $893,750 holds the middle half of loans, a tight spread. The program count is 21 for 7(a) and 13 for 504, a healthy share of real estate financing. Franchising is 0.00%. Years shown: FY2017 with 7 loans and $6.8 million, FY2018 with 7 loans and $3.2 million, FY2021 with 7 loans and $6.0 million, and FY2025 with no approvals and $0. On SBA's books Wells Fargo Bank National Association carries 8 loans worth $5.1 million, and Live Oak Banking Company carries 5 worth $6.7 million. Those are holder entries, silent on origination.

Floors that do not appear

For Sonoma County, no floor for cancellations or for charge-offs is printed. Loan Analytics could not stand behind a rate from so small an early disbursement group, so read the gap as unknown.

Study points for a Sonoma County practice

The study should begin with patient demand within a drive of the site, then look at the number of dentists already practicing nearby and the payer mix the new office can reasonably expect. A new-build or tenant improvement budget must account for treatment rooms, imaging and sterilization, and for dental offices that is a large share of cost. Buying a going practice versus opening a new one changes the timing: a purchase brings collections at once, while a start-up absorbs months of losses. Debt coverage should be tested on haircut collections, and the appraisal should split property value from a patient list's goodwill, which may not follow the dentist.

Both rates are floors. SBA withholds the status of open loans, so a loan counts as charged off only once SBA reports it; a rate needs at least 30 loans in its cohort and is otherwise not reported.

CountyLoans
Sonoma County, CA34

Counties with 5 or more loans; smaller ones are not listed.

Metro is the CBSA (metropolitan or micropolitan statistical area) of the loan's project county, July 2023 delineation (OMB Bulletin 23-01). The county is matched by name (manifests/ld2/county-cbsa-map.csv); a loan whose county cannot be placed in a 2023 CBSA is left out of every metro.

A value marked withheld rests on fewer than 5 loans, or is withheld so that such a figure cannot be derived from other published figures.
