What is a cap rate in UK property investment?

Cap rate (Capitalization Rate) is the ratio of Net Operating Income (NOI) to property value. Formula: Cap Rate = (Annual NOI / Property Value) × 100. In the UK, cap rates typically range from 3-10% depending on location and property type. Higher cap rates mean higher returns but potentially higher risk.

What is a good cap rate for UK buy-to-let?

A good UK buy-to-let cap rate is 4-7%. London properties average 3-4%, while Northern cities average 6-8%. Commercial properties typically have higher cap rates (6-10%). Consider your risk tolerance and location when evaluating cap rates.

How do I calculate net operating income?

Net Operating Income = Annual Rental Income - Operating Expenses. Operating expenses include: property management, insurance, maintenance, ground rent, service charges, and letting agent fees. Mortgage interest is NOT included in NOI (it's part of financing).

Is cap rate the same as yield?

Cap rate and rental yield are similar but not identical. Rental yield = (Gross Rental Income / Property Value) × 100. Cap rate = (Net Operating Income / Property Value) × 100. Cap rate accounts for expenses, making it a more accurate measure of investment performance.
