Comparing a 7.72% 30-year fixed mortgage on a MX$25,650,000 purchase

I have checked the quoted rate and basic monthly payment, but the true cost and flexibility remain unclear. The offer is 7.72% over 30 years for a Mexico City purchase of about MX$25,650,000, and the final pricing depends on fees and the applicable loan-to-value band.

I am trying to compare lenders over the period I might actually own the property rather than relying only on the headline rate. The payment difference is fairly small, so restrictions on early repayment or transferring the mortgage could be harder to undo later. I also need confirmation that the rate is fixed for the entire term rather than subject to any reset.

Which figures would you place side by side: standardized annual cost, fees paid in cash, interest during the likely ownership period and the remaining balance at exit? I am also asking whether the energy label affects pricing or is merely required information.
 
The practical constraint is your likely exit date, because few buyers keep the same loan for all 30 years. I would model the offers to a cautious ownership horizon and include closing fees, ongoing loan charges, interest, any repayment penalty and the balance still owed at that point.

That should not depend on assuming an easy refinance. Run a second case in which you have to keep the mortgage longer than planned, then check whether the cheaper short-term option still holds up. Monthly affordability remains a separate pass-or-fail test.
 
What loan-to-value are they actually quoting, and are the arrangement fees paid at closing or added to the loan? Those details could explain much of the gap from the advertised rate. I would also ask whether the energy label changes the pricing or is simply information requested for the property.
 
I slightly disagree with using a personal holding period as the main comparison. It can make a weaker offer look better through an optimistic refinance assumption. Start with the lender's standardized annual cost figure, then model your own timeline as a second step.
 
Since the payment difference is small, put a value on flexibility rather than treating it as a vague benefit. Run three cases: keep the mortgage, make occasional overpayments, and sell before year 30. That should reveal whether lower fees or better exit terms actually compensate for the rate.
 
Portability needs more detail. Does it preserve the 7.72% rate, cover only the existing balance, and still require approval for the replacement property? Also ask what happens if the sale and purchase dates do not line up. The word itself may promise more flexibility than the process delivers.
 
I would confirm that “fixed for 30 years” means the rate is fixed for the entire amortization period, not merely that the payment illustration runs for 30 years. If there is any reset or repricing mechanism in the contract, that risk belongs in the comparison.
 
These questions are helping. I had been comparing the headline rate and monthly payment too closely. I will ask each lender for the same loan-to-value scenario, an itemized list of fees, the remaining balance at several possible exit dates, and the exact wording on portability and early repayment.
 
Good plan. Make sure the advertised lower rate is available at your actual loan-to-value rather than only under a different tier. Otherwise you are not comparing the quote with a real alternative, just with marketing.
 
Do not overlook cash needed at completion. Two offers can have similar long-run costs but very different upfront demands. If paying the arrangement fee reduces your available buffer after purchasing a MX$25,650,000 property, that may matter more than a small monthly saving.
 
A simple sheet should be enough: initial cash, monthly payments, one-off and recurring fees, optional overpayments, exit charges, and balance remaining on each comparison date. Keep any assumed refinance rate in a clearly separate column so it does not quietly determine the winner.
 
On portability, I would ask for examples covering a cheaper replacement property, a more expensive one, and a gap between transactions. No need to assume all three are allowed; the point is to see precisely where a new approval or different rate could enter.
 
That said, I would not pay much extra for portability unless moving during the fixed period is a credible possibility. Early-repayment flexibility is usually easier to model because you can attach it to specific overpayment amounts and dates.
 
Ask competing lenders to quote the identical purchase price, loan amount, term and fee-payment method. The loan-to-value issue makes this especially important. Even a clean-looking APR comparison loses value if one lender has assumed more equity or financed the fees differently.
 
For early repayment, distinguish regular permitted overpayments from full repayment after a sale or refinance. Ask for the charge in each case and whether the terms change over time. The relevant language is whatever appears in the proposed contract, not a verbal description of “flexible.”
 
One missing affordability point: is the household income in Mexican pesos or another currency? If income and the mortgage are in different currencies, testing exchange-rate changes could matter more than the small payment difference between these offers.
 
Agreed with Sam. Currency mismatch, if there is one, should be tested separately from interest-rate risk. Even with a genuinely fixed 7.72% rate, the payment can become less affordable relative to income if that income is received elsewhere.
 
For the affordability test, I would use the actual quoted payment plus ongoing ownership costs, then reduce income or increase other expenses in a few scenarios. Avoid assuming that refinancing will rescue a tight budget; treat it as an option, not the base case.
 
The same conservative treatment should apply to portability. Give it no financial value in the spreadsheet until the lender confirms what is preserved and what remains subject to approval. Then you can decide whether the confirmed benefit justifies any extra fee or rate.
 
Has the lender explained why the energy label appears in the mortgage discussion? I would ask whether it affects eligibility, the quoted rate, fees, or nothing at all. That keeps an ancillary property detail from being mistaken for a financial concession.
