How Much Down Payment Does a Conventional Loan Require?

Published 2026-09-09 Last reviewed 2026-09-09 By Lisa C Hamilton, REALTOR®

Quick Answer

No, a conventional mortgage does not universally require 20% down. Fannie Mae currently describes certain eligible conventional loan options with down payments as low as 3% of the purchase price. The actual minimum depends on borrower eligibility, occupancy, property type and loan program.

Where Did the 20% Myth Come From?

Twenty percent is important because conventional borrowers below a certain equity level may need PMI.

But:

“PMI may apply below 20%”

is not the same statement as:

“You cannot buy below 20%.”

Example

$500,000 purchase:

  • 3% = $15,000
  • 5% = $25,000
  • 10% = $50,000
  • 20% = $100,000

Those differences can dramatically affect cash reserves.

Why Put More Down?

Potential benefits:

  • Lower loan amount
  • Lower payment
  • Potentially lower PMI
  • More immediate equity

Why Put Less Down?

Potential benefits:

  • Preserve cash
  • Maintain emergency reserves
  • Keep money for repairs
  • Invest elsewhere
  • Avoid delaying purchase

What Is the Right Amount?

Ask the lender to model multiple scenarios.

For example:

  • 5% down
  • 10% down
  • 20% down

Compare:

  • Rate
  • PMI
  • Monthly payment
  • Cash remaining
  • Closing costs

Use the mortgage calculator and affordability calculator to see how the choices interact.

First-Time Buyers

Some conventional low-down-payment programs are specifically designed around first-time or income-qualified borrowers.

Eligibility rules vary.

Investor Properties

Do not assume primary-residence down-payment structures apply to investment properties.

Investor requirements can be significantly different.
