Free Move-Up Buyers Mortgage Calculator (2026)
Plan your upgrade with side-by-side payment comparisons
Why Move-Up Buyers Matters
Moving from your starter home to your next property requires careful financial planning, especially when juggling two mortgages or timing a sale and purchase. Our Mortgage Calculator lets move-up buyers compare their current payment against projected payments on their target home. Model scenarios including using your home equity as a down payment, bridging between properties, and evaluating whether to sell first or buy first.

Frequently Asked Questions
Selling first gives you certainty about your available funds and eliminates the risk of carrying two mortgages. However, you may need temporary housing between properties. Buying first avoids disruption but carries financial risk if your current home takes longer to sell. A bridge loan or home equity line of credit can help manage the overlap period. Your decision depends on your financial cushion and local market conditions.
Your home equity (current market value minus remaining mortgage balance) can fund part or all of your next down payment. A larger down payment from equity means a lower loan amount, potentially no PMI requirement, better interest rates, and lower monthly payments. Calculate your realistic net proceeds after selling costs (typically 6-10% of sale price) to determine your available equity for the next purchase.
Interest rates are primarily determined by market conditions, credit score, and loan type rather than the home price. However, loans exceeding conforming loan limits (jumbo loans) may carry slightly higher rates. If you have had your current mortgage for years at a low rate, the payment increase from both a higher loan amount and a higher rate can be significant. Our calculator helps you model these scenarios.
