You will want to speak to a mortgage specialist to see what you are pre-qualified for based on income, credit score & debt. You will then receive your answers. Best of luck!
Your best bet will be to speak with a lender! They are the ones who are truly able to answer those questions! It can be tricky to navigate the home buying process. Make sure you have a great team who are there to educate you and have full transparancy through the transaction!
If you are hoping to buy a house, you likely have a budget in mind. Hopefully, that budget includes fees that come with the process, not just the purchase price. The good news for buyers is that they aren't directly responsible for paying their agent. Agent fees usually fall on the seller.
