Free mortgage calculators for Reading & Caversham buyers

A residential mortgage is a loan secured against a property that you intend to live in as your main home. Unlike buy-to-let mortgages (which are for rental properties) or commercial mortgages (for business premises), residential mortgages are specifically designed for owner-occupiers.

Residential mortgages come in many forms to suit different situations. You might be a first-time buyer taking your first step onto the property ladder, a home mover looking to upsize or relocate, someone wanting to remortgage to get a better deal, or a self-employed person needing specialist consideration of your income.

The mortgage market has hundreds of different products from dozens of lenders, each with different criteria, rates, and features. That is where we come in. As mortgage brokers, we search our comprehensive panel of lenders to find mortgages that match your specific circumstances: income; deposit; and preferences. We then explain your options in plain English and handle all the paperwork from application through to completion. We can also recommend quality solicitors to assist with all your legal and conveyancing needs.

Tick the box above if you are a non-UK resident to add the 2% surcharge to every band.

As a rule of thumb: 60% LTV or below unlocks the best rates; 75–85% covers most movers; 90–95% suits first-time buyers with smaller deposits. Above 95% LTV is rare and usually requires a guarantor or specialist product.
