Nothing set by law, but check with lenders to find out their guidelines. Many lenders discourage the smaller sized mortgages………and be aware that the best rates offered by most lendrs are for loans of $150,000 or $200,000 and up.
So generally there is no minimum amount required to refinance….but….there is an effective minimum. What I mean by that is, on smaller mortgages it’s often not worth the expense to refinance to save even 1% in interest rate. The reason for this is that most of the closing costs associated with refinancing are fixed. There is very little difference in $ cost in refinancing a $50,000 mortgage or a $250,000 mortgage.
Let’s say refinancing costs are $2500 and you’re considering refinancing to save 1% on your mortgage. If you owe $250,000 the 1% savings is $2500/yr. If you owe $50,000, your 1% savings is only $500. The $2500 is costs is recovered in 1 year with the $250,000 refinance, whereas it will take the $50,000 mortgage applicant five years to recover the costs.
Check with your lender regarding refinancing feasibility for you. Reputable, professional lenders will show you your cost of refinancing and your “breakeven point” for recovering those costs……….ST
