Refinancing hiccups-debt to income ratio

[Caleb Dryden]

My real estate portfolio is growing and as it does I'm having trouble continuing the BRRRR strategy. I have a 9-5 job, no debt, other than the properties I've BRRRR'd and refinanced, thus picking up a loan in the end. I'm figuring banks will soon restrict my ability to refinance since the gap between my debt/income ratio is growing. Any suggestions/thoughts on tweaks I can make to avoid slowing down my progress? Thanks for your time...
