Hello @Stone Denning! I am excited for you beginning your journey. You are definitely going to want to talk to a lender sooner rather than later. They are going to be able to tell you what you would currently qualify for and what sort of paperwork/debt paydown you would need to qualify for the price range you are interested in.
Generally speaking, FHA loans are easier to qualify for since they are backed by the government. Once again, talk to a lender but as a business owner generally two years of P/L statements and tax returns are preferred to qualify your income and allow the lenders to determine the income side of housing expense ratio (HER). FHA loans typically require a HER of 31% or below if you were to calculate monthly PITI (principal+ interest+ taxes+ insurance+ mortgage insurance premium) divided by monthly gross income. Additionally, FHA loans typically require 43% or below for your total obligations ratio (TOR) which in addition to your housing expenses includes long-term debt payments such as a car loans or student loans. This total obligations number is also divided by gross monthly income. Finally, you will be able to add some of the anticipated rents from the investment property to your gross monthly income as well.
My advice: don't take on any more debt in the short-run, play around with those calculations to get a sense of where you stand, talk to a lender, and make sure your business accounting is being done properly (consider working with a CPA if you do not already).
Good luck and feel free to reach out anytime!
