The most important thing that the guys didn't explain well before is the issue of terms and interest rates. It's not the same as a regular loan - since you're putting up your property as collateral, the bank wants to make sure they can collect the debt if you don't pay, so they're going to get your property appraised (that costs money, like a few hundred) and check if the value is enough to cover the loan you want. Depending on how much you're asking for and your property's value, the interest rate changes a lot. It's usually lower than a personal loan because the bank is taking less risk, but you need to be prepared for long terms - most of them are 10, 15, even 20 years of financing.
In the bank's app the process starts with you going into the credit menu and looking for "mortgage" or "loan with property guarantee." You fill in the basic info (how much you want to borrow, what it's for, what timeline you're thinking), and then they schedule that property appraisal. You're gonna need to get documents like the property deed, proof of income, bank statement, maybe even a copy of the lien notice if the property has previous financing. Some banks let you do all of this through the app, others ask you to go in person or do a video call to sign documents - depends on the institution.
One thing worth paying attention to: read the fine print about early payment. Some banks charge a penalty if you want to pay off the loan faster, others let you do it free. If your plan is to renovate and then maybe sell or refinance later, that makes a difference in your wallet.
