Higher rent and a rising gross rental yield do not prove that an investment property is cash-flow positive. Vacancy, operating costs and the actual loan cost still determine the monthly result.
More property listings may improve negotiating room, but a lender valuation below the contract price can increase the cash contribution needed to complete the purchase.
A longer contractual term or interest-only period may reduce scheduled repayments, but borrowing capacity and total interest depend on separate calculations.
A lower purchase price may improve the entry maths, but rent still needs to cover vacancy, holding costs and finance—or household income must fund the gap.
