Do you think I’ll be able to qualify for conventional loan for investment property?

Apologies if I’m all over the place and overcomplicating things but here’s the situation, a year ago I was 30k in cc debt and have been chipping away at it and now have 15k left. Now that I’ve decided what I want to do with my money instead of continuing to save up and slowly pay off debt I’m just going to pay off all my debt to increase my credit score in order to be able to start investing in real estate.

In the next month I’ll have more than enough to pay off my cc debt and still have a decent savings left over. In the next 2-3 months I plan on having cc debt and my car loan paid off. I’m hoping credit score will slowly go back up to 750 where it was before all the cc debt (at a 650 now).

I’ve only started making enough money to even qualify for a conventional loan for a decent house in the past 6 months. Before that I was making less than 48k. So I’ll wait another 6 months to start applying, by that time I’ll have had no debt for 4 months and made 100k+ in a year. But with the shaky credit card history and only having had made 48k the year prior how realistic is it that I will qualify for a conventional loan with 20% down?
