First-Time Buyer Mortgages: The Schemes, and the Catches
Every market has a set of arrangements aimed at people buying their first home, and they all solve the same problem: the deposit and the taxes are the barrier, not the monthly payment.
They also all have a cost, and the cost is rarely on the front of the leaflet. It is usually a higher rate, a slower path to equity, or a constraint on what you can do later.
What actually blocks a first purchase#
Worth naming, because the schemes are designed around it. For most first-time buyers the monthly payment is affordable — often lower than the rent they are already paying — and the obstacle is the lump sum: deposit, plus transfer tax, plus fees, all of it in cash on one day.
- The deposit, which grows as prices grow, so saving chases a moving target.
- Purchase taxes, which are cash and cannot be borrowed.
- Legal and lender fees, which are small individually and add up.
- Furnishing and immediate repairs, which nobody budgets and everybody pays.
- In several markets, the higher rate charged at high loan-to-value, which makes the payment worse exactly when the deposit is smallest.
The common scheme types#
| Type | How it helps | What it costs |
|---|---|---|
| High-LTV product (95%) | Buy with a small deposit | Highest rate band; slow equity build |
| State guarantee | Lender protected, so high-LTV lending exists | Usually a rate premium; eligibility rules |
| Tax reduction or exemption | Cuts the cash needed at completion | Price caps and residence conditions |
| Shared ownership | Buy a share, rent the rest | Rent plus service charge; harder resale |
| Family guarantor or deposit | Family income or savings support the application | Real risk transferred to the family member |
| Subsidised savings account | Bonus on money saved for a deposit | Contribution limits and a waiting period |
Schemes change frequently — they are policy instruments and they appear, tighten and end with budgets. Check the current rules with the national body rather than an article, including this one.
The catches, stated plainly#
- High-LTV rates are genuinely higher, and the difference applies to the whole loan for the whole product period.
- Small deposits build equity slowly, so a modest price fall can put you in negative equity and unable to remortgage.
- Price caps on tax reliefs and schemes distort what you look at, and can push buyers to the edge of the cap.
- Shared ownership combines a mortgage with rent and a service charge, and resale is often slower and more restricted.
- Guarantor arrangements move real risk onto a family member — often a parent’s home or savings.
- Newbuild premiums matter because many schemes are only available on newbuild, which can be priced above the resale market.
None of these makes the schemes wrong. They make the comparison a real comparison rather than a leaflet.
What to do first#
- Calculate the full cash requirement in your market: deposit, transfer tax, notary and legal, lender fees, moving.
- Check which LTV band your realistic deposit reaches, and what the next band would cost to reach.
- Find the current national scheme rules from the government or regulator, not from an article.
- Get an affordability view from a broker before falling in love with a property.
- Clean up short-term debt and unused credit limits three to six months ahead.
- Compare the scheme product against the plain product at the same LTV — sometimes the scheme is not the cheaper route.
Step six is the one most often skipped. A guarantee scheme that costs half a point more than an ordinary 90 per cent product is worth taking only if you cannot reach 90 per cent.
The rent comparison, done honestly#
Buying is often compared with renting on the monthly figure alone, which flatters buying. An honest comparison includes the things a tenant does not pay: maintenance and repairs, buildings insurance, service charges where they apply, purchase and eventual selling costs spread over how long you will actually stay, and the interest itself, which is the cost of the money rather than a payment into an asset.
- Maintenance is commonly budgeted at around one per cent of the property value a year.
- Purchase and sale costs together can consume several years of any price growth.
- The capital portion of the payment is saving; the interest portion is a cost, like rent.
- Staying under about five years rarely recovers the transaction costs.
- Owning removes rent increases, which is a genuine long-term advantage the monthly comparison hides.
The honest summary is that buying usually wins over a long horizon and frequently loses over a short one, and the transaction costs are what decide where the line sits.
Frequently asked questions
How much deposit does a first-time buyer need?
It depends far more on the market than on being a first-time buyer. Five per cent products exist in the United Kingdom and elsewhere, ten per cent is a common practical minimum, and the Netherlands still permits borrowing the full price — while Germany and Spain expect around twenty per cent and add purchase costs of a tenth of the price on top. The number that matters is total cash needed at completion, not the deposit percentage alone.
Are first-time buyer schemes worth it?
Sometimes, and the test is a direct comparison rather than the leaflet. Compare the scheme product against an ordinary product at the same loan-to-value. If you could reach the ordinary product with the deposit you have, the scheme frequently costs more in rate than it saves elsewhere. If the scheme is what makes the purchase possible at all, that is a different question — but check the resale restrictions, the price caps and, for shared ownership, the rent and service charge alongside the mortgage.
Is it better to rent or to buy?
Over a long horizon buying usually wins, over a short one it frequently loses, and transaction costs decide where the line falls. An honest comparison adds what a tenant does not pay: maintenance at roughly one per cent of the value a year, buildings insurance, service charges, and the purchase and eventual sale costs spread across how long you actually stay. Under about five years those costs rarely recover. The genuine long-term advantage of owning is that the payment stops rising while rent does not.
