The most expensive misconception in first-time home buying is that you need twenty percent down. You almost certainly do not, and Pennsylvania has assistance programs that go consistently underused because nobody explains them at the point where they would matter.
Start with the loan itself
Before assistance programs, understand the baseline. Conventional loans go as low as 3% down for qualified first-time buyers. FHA loans go to 3.5% and are more forgiving on credit. VA loans can go to zero down for eligible service members and veterans. USDA loans can also go to zero down in eligible rural areas — and parts of northern and western Chester County genuinely qualify, which surprises buyers who assume USDA means farmland.
Each has tradeoffs, mostly around mortgage insurance. Conventional PMI can be removed once you reach sufficient equity. FHA mortgage insurance generally stays for the life of the loan at low down payments. That difference compounds over years and belongs in the comparison.
PHFA
The Pennsylvania Housing Finance Agency is a state agency that offers mortgage products for first-time buyers, purchased through participating lenders rather than directly from PHFA. Its programs frequently carry competitive rates and are paired with assistance options.
The one worth knowing by name is Keystone Advantage Assistance, which provides down payment and closing cost assistance in the form of a second mortgage. There are also PHFA programs oriented toward buyers purchasing homes that need repairs, and programs for buyers with a disability or a household member with a disability.
Eligibility generally turns on household income limits and purchase price limits, both of which vary by county, plus a homebuyer education requirement. Those limits change periodically. Rather than trusting any article — including this one — on the current figures, confirm them with a PHFA-participating lender at the time you are shopping.
County-level programs
Both Montgomery County and Chester County have operated first-time homebuyer assistance programs, typically funded through federal HOME or CDBG allocations and administered through the county or a partner housing agency. These are usually structured as deferred or forgivable loans for down payment and closing costs, with income limits set relative to area median income and a required owner-occupancy period.
Funding for these programs is finite and application windows can open and close. If you are within a year of buying, it is worth calling the county housing office early to find out where the program stands rather than discovering it after you are under contract.
The number people forget
Down payment is not the only cash you need. Closing costs in Pennsylvania typically run 2–5% of the purchase price and include lender fees, title insurance, and Pennsylvania's realty transfer tax — which is commonly split between buyer and seller and varies by municipality. You will also want reserves after settlement, because the first month in a house reliably produces expenses nobody budgeted for.
Use an affordability calculator to work backwards from your actual monthly comfort level rather than forward from a pre-approval maximum. The pre-approval tells you what a lender will allow. It does not tell you what you should spend.
The sequence that works
Talk to a lender before you look at houses — ideally one that participates in PHFA programs. Find out what you qualify for and what assistance is available. Complete the homebuyer education requirement early if a program requires it, because it takes time. Then start looking, with a real budget instead of a hopeful one.
If you want an introduction to lenders who actually work with these programs in Montgomery and Chester County, just ask. There is no charge and no obligation for that conversation.
