How to accurately calculate the loan repayments?
I want to make sure I can repay the loan on time.

Why don't you try to google calculators? There are tons of websites providing calculators. Test few of them to get a whole picture

Google calculator does not take into account possible payments. To do this, it is best to use the online credit calculator https://www.mlcalc.com/
This takes into account both tax payments and payments under insurance contracts. You can also calculate payments based on the down payment

This is interesting, but are you sure you calculated the cost correctly? I also want to take out a loan to buy a home and I'm looking for good conditions for a long-term loan.

If you are looking for a company that is ready to provide you with an installment loan on good terms and with a low interest rate, then I know one site where you can get help with this. Here https://maybeloan.com/installment-loans is a description of what installment loans in USA service is and how to get money on credit from this company. It seems to me very convenient when you apply for a loan online and receive a response from an employee of a credit company within an hour.
