How to keep growing with Debt to Income Ratio

[Bradyn Melser]

Hey BP fam. I am a newer investor. I have 2 rental properties - one I just bought to get into the REI game, the second I did a BRRR. I really enjoy real estate and want to continue growing my portfolio. I have a decent amount of cash, and access to private funding. However, with only 2 homes my debt to income ratio is almost maxed. These are my ONLY sources of debt. I don't bring in tons of money, but am in a career where I am able to save most of it (about 1.6k a month). Also both of the rentals are under a year old, so I haven't shown income on taxes yet.

So my question is this: Is there a way to keep growing this faster than just saving to buy a property cash? It seems like I hear of these people who are buying 10-20 properties a year... How do they do that without overextending their D2I ratio?
