A stack of paperwork used to sit mostly unopened in a lot of Foster City condo files: the HOA's reserve study, the master insurance declarations page, board minutes noting whether a special assessment was ever on the table. If a buyer brought a large enough down payment, the loan often moved through a Fannie Mae or Freddie Mac review path called Limited Review or Streamlined Review, and that stack got a glance instead of a read.
As of August 3, 2026, that path is gone. Fannie Mae's Lender Letter LL-2026-03, matched the same day by a Freddie Mac bulletin, retired Limited Review for conventional condo loan applications dated on or after that date. Nearly every condo project with more than ten units now goes through Full Review, no matter how much cash the buyer is putting down. That single change reshapes how a Foster City condo or townhome deal gets financed, because Foster City is not a market where attached homes are a side category. City planning data from the 2023-2031 Housing Element shows single-family attached, small multifamily, and larger multifamily housing together make up roughly two-thirds of the city's residential stock as of 2020. A rule built around condo underwriting was never going to be a footnote here.
What Full Review Actually Checks
Full Review means the lender examines the HOA's budget, reserve funding, delinquency rate, insurance coverage, and litigation history before the loan can move forward, regardless of the loan-to-value ratio. That is a different conversation than most Foster City buyers have had in the past several years.
Three pieces of that review carry the most weight right now:
- Reserve study currency. If the HOA's reserve study is more than 36 months old, lenders are flagging it. The study has become the document that determines whether a building can be financed at all, not just whether the dues look reasonable.
- Reserve funding level. Baseline funding, where an association lets its reserve balance drift toward zero between big expenses, no longer passes muster. Fannie Mae's updated guidelines require associations to fund at the highest level their own reserve study recommends if they fall short of a 15 percent contribution threshold, a requirement phasing in for Full Review files by January 4, 2027.
- Master policy deductible. For applications dated on or after July 1, 2026, a master property insurance policy with a per-unit deductible above $50,000 makes the project non-warrantable outright.
None of this touches the buyer's credit or income. It is entirely about the building.
Why This Lands Harder in Foster City Than Elsewhere on the Peninsula
MLSListings' June 2026 snapshot for Foster City shows 28 active condo and townhome listings against 10 active single-family listings, with attached homes trading at a median price per square foot of $685 compared to $1,129 for detached homes. That gap has always been part of the entry-point story for buyers priced out of the single-family tier. What changes now is that the entry point itself runs through a financing review that did not used to apply evenly across price points.
The city's older, denser waterfront pockets carry more of this exposure than its newer subdivisions. Marina Point, laid out along streets named for ship parts like Mainsail Court and Topsail Court, has no waterfront single-family inventory at all. Its waterfront parcels are condominiums and apartment buildings. The Islands neighborhood, built around a 174-unit complex recognized by Architectural Record in 1976, carries a similar concentration of attached product. In neighborhoods like these, a buyer's ability to close now depends as much on the HOA's paperwork as on the buyer's own file.
The Waiver of Project Review, which lets small buildings skip this scrutiny entirely, was expanded this year from buildings of four units or fewer up to buildings of ten units or fewer. That is real relief for a handful of Foster City's smallest condo conversions. It does very little for the larger complexes that make up most of the city's attached inventory, where unit counts typically run well past ten.
What to Pull Before You Write an Offer
For a buyer, the practical shift is timing. Reviewing the HOA's file used to be something a lender's underwriter did somewhere in the middle of escrow. Now it belongs at the front of the process, before an offer goes in.
- Ask the HOA management company for the reserve study date and funding percentage before submitting an offer, not after opening escrow.
- Ask specifically whether the master insurance policy's per-unit deductible sits above or below $50,000.
- Ask about any special assessment activity in the past three years and whether one is currently under discussion.
- Confirm with your lender, in writing, whether the building has a known Full Review outcome on file already. Some lenders retain prior review results for buildings they have financed before, which can save weeks.
A buyer who skips this and falls in love with a unit first can end up with a signed contract and no conventional financing path if the building's reserve study turns out to be four years old with a baseline funding plan. Cash purchases and non-warrantable portfolio loans remain available in that situation, but they typically carry higher rates, larger down payment requirements, and a smaller pool of lenders willing to write them.
What This Means If You're Selling
For sellers and HOA boards, the incentive has flipped in a useful direction. A building with a current reserve study, adequate funding, and a compliant insurance deductible now closes conventional loans faster and to a wider buyer pool than a building without one. That is a marketable fact, not just a compliance requirement.
If your association's reserve study is approaching the three-year mark, getting it updated before listing season removes a friction point that would otherwise surface mid-escrow, at the worst possible time for a seller trying to hold a timeline together. The same logic applies to a master policy renewal that quietly drifted above the new $50,000 deductible threshold. Fixing that at renewal is a board decision. Discovering it during a buyer's loan underwriting is a delay nobody wanted.
Frequently Asked Questions
Does this change anything for single-family home purchases in Foster City? No. LL-2026-03 governs condo and PUD project review. A detached single-family purchase is unaffected by this specific rule change.
If I'm putting 40 percent down, do I still need to worry about this? Yes. That is the core of what changed. Down payment size no longer determines whether a lender does a light or full review of the HOA. Nearly every condo project over ten units gets a Full Review now, regardless of loan-to-value.
What if the building I want fails Full Review? The loan can still close through a cash purchase or a non-warrantable portfolio loan, but expect a larger down payment requirement and a higher rate than a standard conventional loan would carry. Talking with a lender before writing an offer, not after, is what keeps that option open rather than forcing it.
Does this apply to townhomes as well as condos? It depends on the legal structure. Some Foster City townhome communities are organized as PUDs with fewer shared ownership elements, which can qualify for simpler review paths. Others are structured more like condominiums. Ask your lender early which category applies to the specific building.
This is the kind of detail that used to live in a loan officer's back pocket and now belongs in the first conversation about any Foster City condo or townhome purchase. If you are weighing a specific building, or you sit on an HOA board wondering whether your reserve study needs an update before your next listing season, Julie Flouty can help you read the file before it becomes a problem instead of after.
