Four ways to pay for a typical home in Warren County

For a typical $105,000 home at Freddie Mac's average rate (7.18% as of November 5, 2026) over 30 years. The monthly payment adds principal and interest, the county's property tax, an example homeowners insurance and mortgage insurance when it applies.

  • Cash to close = down payment plus 3% of the price in closing costs (example).
  • Minimum score: FHA requires 580 or higher for the minimum down payment (HUD Handbook 4000.1). * Fannie Mae requires 620 when a loan is underwritten by hand; its automated system has no fixed minimum.
  • The ITIN row is an example with a rate 1 percentage point higher: ITIN loans follow no federal rule and each lender sets its own down payment and rate. Nothing in this table promises an approval.

Loan limits

FHA loans in Warren County use the national floor limit: it isn't a high-cost area. If the loan you need is above these amounts, it doesn't fit FHA or it becomes a "jumbo" loan.

VA loans. If you have full VA entitlement, VA doesn't cap the loan amount. If you've used part of your entitlement, the calculation uses the county limit ($832,750 for one unit). VA loan limits (va.gov)

USDA loans. They're for homes in eligible rural areas and households with incomes within USDA's limit. Check whether the address and your income qualify on the official site. USDA eligibility (usda.gov)

Is there a flood risk?

FEMA’s maps count no homes in high-risk flood zones in Warren County. That does not mean there is no risk: some areas have no map. Check your address.

  • A high-risk zone (Special Flood Hazard Area) has a 1% or greater chance of flooding each year. (44 CFR 59.1)
  • If the home is in that zone and the loan comes from a regulated lender, federal law requires flood insurance for the life of the loan, in communities that take part in the NFIP. (42 U.S.C. 4012a)
  • Most homeowners insurance does not cover flood damage. (FEMA, FloodSmart)

Climate and upkeep

Department of Energy (PNNL), 2021 IECC zones

The home energy code (IECC) puts Warren County in zone 5A: cold.

The zone's number says how hot or cold it gets; the letter says how humid: A is moist, B is dry and C is marine.

  • Spring

    • Book the air conditioner's check-up before the heat: ENERGY STAR advises checking the cooling system in the spring, because contractors get busy once summer comes. ENERGY STAR (EPA)
    • Clean and repair the roof gutters. EPA

  • Summer

    • Seal the air ducts that run through the attic, crawlspace, basement or garage with duct mastic or foil tape, then wrap them in insulation. ENERGY STAR (EPA)
    • Check that the ground slopes away from the house, so water does not collect around the foundation. EPA

  • Fall

    • Book the heating check-up in the fall. If it runs on gas or oil, the technician should check the connections: faulty ones are a fire hazard. ENERGY STAR (EPA)
    • Seal air leaks and add insulation in the attic: ENERGY STAR says it lowers the chance of ice dams on the roof in snowy climates. ENERGY STAR (EPA)

  • Winter

    • Get the house ready for the cold with insulation, caulking and weather stripping, and learn how to keep pipes from freezing. Ready.gov (FEMA)
    • Put clear plastic film over the windows: it is inexpensive, cuts drafts, helps the house feel warmer in winter and reduces moisture on the glass. ENERGY STAR (EPA)

All year

  • Check the air filter every month, especially in heavy-use months. If it looks dirty, change it; change it at least every 3 months. ENERGY STAR (EPA)
  • Test the smoke alarms every month and replace their batteries at least once a year. USFA (FEMA)

Each task comes from the official page beside it. The spring air-conditioning and fall heating check-ups are the timing ENERGY STAR advises; the rest is a suggested order.
