I can't give you any advice about your DTI, because the numbers are what they are. If your DTI is too high for a conventional loan, then think about other possibilities that will lower it while still meeting your goals. I would focus on finding something below market that requires light rehab, but can yield substantial rents. Once you refi a property like this out and pay back your lenders, you should build more room into your DTI for future acquisitions.
I know, deals like that are hard to find. However, they are not impossible. It doesn't sound like you are in a hurry. You have time to get to know your market, research tax records, and build some leads. You only need one. FB Marketplace can be a good place to look as well. In the meantime, talk to lenders, make wealthy friends (private money), hang out with realtors who have their ear to the ground, and let everyone who will listen know what you are looking for.
