Before buying a property you need to ask an estate agent on what estimated value the property yields when rented every month. The Rental Income will then be deducted by the following expenses:
- Insurance Premiums
- Replacing fixtures and fittings
- Ground Rent and service charges if the property is leasehold
- Void periods
- Letting Agency Fees
- Mortgage costs
Once everything mentioned above is deducted from your gross rental income then you can have your net income.
