The single most important factor in a new build purchase is how long your mortgage offer stays valid. If you reserve a plot that will not be finished for eight months and your lender's offer expires after six, you will have to re-apply at whatever rates apply then. Choosing the lender for the build timetable matters more than choosing it for the headline rate.
Leicester has a lot of new build activity — Enderby, Narborough, Glen Parva, Whetstone and the New Lubbesthorpe development on the south-west edge of the city. These are popular with first time buyers and home movers alike.
Offer validity is the whole game
A standard purchase completes in twelve to sixteen weeks, comfortably inside any lender's offer period. A new build bought off-plan is different — you might reserve in spring and complete in autumn.
Lenders vary considerably:
- Many issue offers valid for three to six months
- A smaller group extend to nine months or more, specifically for new build
- Some will extend an existing offer on request; others require a fresh application
If the offer lapses and you re-apply, you get current rates, a fresh credit check and updated income evidence. If rates have risen, so has your monthly payment — on a house you have already committed to.
Ask the developer for a realistic completion window before you apply, then we choose a lender whose offer outlasts it, with margin.
Developer incentives have a ceiling
New build sales frequently come with incentives — a deposit contribution, stamp duty paid, flooring and appliances included, sometimes part-exchange on your existing home.
All of it must be declared to the lender, and most lenders cap total incentives at a set percentage of the purchase price. Above that cap, they reduce the loan by the excess.
The practical effect: a package that looks like it reduces the cash you need can instead reduce the amount you can borrow. Get the full incentive list in writing at reservation, and let us check it against the lender's rules before you exchange.
Down valuations
New build valuations sometimes come in below the agreed price. The reason is straightforward — a surveyor values against comparable evidence, and a brand-new home carries a premium that resale comparables do not reflect.
If it happens, the options are to make up the difference in cash, negotiate with the developer, or challenge the valuation with better comparables. On a large site with recent sales, a challenge sometimes succeeds.
It is worth knowing this is possible before you commit, rather than discovering it three weeks before exchange.
Reservation fees and deadlines
Developers usually take a reservation fee and set an exchange deadline, commonly 28 days. That is a tight window for a full mortgage application and legal work.
Two things make it manageable:
- Have your mortgage in principle before you reserve, not after
- Instruct a solicitor who has worked on that development before. They will already have reviewed the site's title and can move faster
Missing the deadline can mean losing the reservation fee, or the plot.
Leasehold and estate charges
Check whether the house is freehold or leasehold, and whether there is an estate management charge for maintaining shared roads, play areas and green space. These charges are common on larger Leicestershire developments and they are an ongoing cost that lenders will factor into affordability.
Ask for the figure in writing at reservation.
Warranty
Nearly all new builds come with a ten-year structural warranty — NHBC or an equivalent provider. Lenders require one. Confirm which provider and that the cover is in place.
Part exchange, and why it affects your mortgage
Several developers on Leicestershire sites offer part exchange — they buy your existing home so you are not stuck in a chain.
It is genuinely useful if you need certainty on timing. Two things to understand before agreeing:
The price will be below open market value. The developer is buying for speed and will resell. You are trading some value for certainty and a guaranteed completion date. Whether that trade is worth it depends on how confident you are of selling conventionally.
It changes your mortgage arithmetic. The equity released from the part exchange becomes your deposit, so a lower agreed price means a smaller deposit, a higher loan to value and potentially a worse rate. Run the comparison properly — a lower purchase price on the new house does not always compensate.
Get the part exchange figure in writing and let us model both routes before you decide.
Snagging and completion
Once the property is finished, you will be invited to inspect it before completion. Take this seriously. Bring a list, or pay for an independent snagging survey.
From a mortgage perspective the relevant point is timing: your lender will release funds on the legal completion date, and defects found afterwards are a matter between you, the developer and the warranty provider. They do not delay or reduce the mortgage. Identify problems before you complete, not after.
Before you reserve
Talk to a broker before you pay a reservation fee, not after. The lender needs to be chosen for the build timetable, the incentive package and the estate charges — and all three are set at reservation.
