Advice for Newbie: pre-qualified, pre-approved or both

[Diamond Bland]

Hello! I have been studying and saving and scouting. I am ready to pull the trigger or start the loading process. I am seeking advice on getting pre-qualified to check what the maximum property price based on my income level. I have not heard much about pre-qualification as much as I have heard about getting pre-approved for a loan. Is it worth getting pre-qualified? Accuracy? Should I do it myself if I know my DTI and the other digits? Will it hurt my score? Can I get pre-qualified at a local credit union, national bank, broker? For context, I am interested in either a conventional or FHA loan depending on the property type. Any advice is welcome. Thank you.
