Factors Affecting Buy-To-Let Mortgage Profitability
1. Purchase Price & Deposit
A higher deposit or lower purchase price reduces mortgage payments, increasing net cash flow.

Even small changes in interest rates can significantly impact monthly payments and overall profitability.

Accurate market research ensures realistic rental income estimates and minimizes risk of negative cash flow.
4. Ongoing Expenses
Maintenance, insurance, management fees, taxes, and utilities directly affect net income.
