The numbers
What it really costs
Built from this home's actual numbers — the most recent property-tax bill on record — not generic estimates.
$5,636 /mo · 10% down Conventional, 30-yr fixed at 6%
The assumptions
Above the FHA loan limit for our service areas, so Conventional is the default. VA buyers: switch below — $0 down.
These numbers assume a generic buyer — your credit, down payment and loan program change them. Get the real quote in minutes:

Value check
Is the price right?
The internet’s favorite home-value number comes from a single automated model that has never seen the street, the finishes, or the view — which is why it routinely misses by tens of thousands of dollars. The edgeAI estimate combines multiple independent data sources with our team’s on-the-ground expertise in this exact market.
