Factors Affecting Buy-To-Let Investment Returns
1. Rental Income
Higher rent increases cash flow and ROI. Market research ensures realistic estimates.

A lower purchase price or higher deposit reduces mortgage payments and improves net cash flow.

Lower interest rates reduce monthly payments, boosting profitability.
4. Ongoing Expenses
Maintenance, insurance, and management fees directly affect cash flow. Accurate estimates are essential.
