Buying new properties on small salary

[Ronald Vargas]

I’m to investing in real estate and i got lucky i bought a house in 2017 and another in 2020. Now I’m sitting on a lot of equity and not sure how to use it. My idea is to buy fixer uppers but i know there’s more to it than that. So my question i have is how do investors get approved loan after loan when let’s say they only make like 60k a year. I thought loan companies look into debt to income ratio as a factor? Also where would you start reading and learning in this forum if you want to learn more about investing in real estate as a rookie
