How the zero-down math actually works
Putting nothing down does not simply move the down payment to zero — it costs you twice. Zero-down programs price above conventional, and they finance a funding fee into the balance, so you start out owing more than the house cost. In Columbia County that difference is worth roughly $161K of purchasing power at a $150,000 income.
The exception is the VA loan. If anyone on the loan is Active Duty, Reserve, or a Veteran, it prices below conventional and charges no mortgage insurance — and the funding fee is waived entirely with any VA disability rating. It is almost always the cheapest zero-down option, and it is worth about $46K more house than a credit-union 100% loan here.
