?? you don't understand the property game..

TS already been paying his outstanding loan for 5 years already.. if the condo was 500k, & he took a 450k loan, in 5 years, the loan outstanding balance is now 340k.. it is reducing..

around 5 years, you should look to refinance to lessen the monthly commitment.. That means TS takes up a fresh 340k loan on the outstanding balance for another 35 years.. So your monthly repayment will also be lesser..

That is how you can reduce your monthly commitment, meanwhile, rental prices generally hover around the same spot. So TS can take advantage of this by renting the unit out at market rate.. Which should definitely be more than his monthly loan repayment...

Do you understand now?.. Unless you are buying the condo at 70% loan, no way you can fight TS monthly commitment after refinancing.. Because his loan is much more lesser than yours.
