I got a long winded answer from my mortgage broker “Most lenders will do 80% LTV on an Investment/Rental Property in Lethbridge. DSCR specific to the Rental Property isn't looked at by many lenders, instead they will look at their personal income and all personal debts, including the new mortgage, taxes and heat giving an overall TDS. The max TDS is 44% in most scenarios, however lenders will allow us to include the potential rental income verified by an Appraisers Market Rents Report. If they have other existing rentals we can also verify this rental income from their tax returns and rental leases.” So i went with the 1.25 Funny thing is the property that seems to be coming out on top is the one i had a cash offer on from the courts but i was out bid in the end.
