My question is on debt to income ratio and how that metric limits your ability to obtain additional mortgages in order to expand your MF residential real estate portfolio.

When I purchase my first MF residential property, with the intent of holding onto to it for the long term, it will be difficult to get approved for another mortgage as I will be close to my debt to income ratio limit.

Are there strategies or suggestions on how to best navigate the debt to income ratio limits for a buy and hold strategy investor?
