Assuming a 30-year fixed-rate mortgage, here’s an estimate of what your monthly mortgage payment, property taxes, and homeowners insurance might be for a $400,000 house with a 20% down payment and a 6% interest rate:

Mortgage payment:
The amount borrowed would be $320,000 (80% of the purchase price), and the interest rate is 6%. Using a mortgage calculator, the estimated monthly payment for principal and interest would be around $1,919.

Property taxes:
Property taxes vary depending on the location of the property. As an example, let’s say the property is located in a county with an annual property tax rate of 1.2% of the home’s value. That would amount to $4,800 per year or $400 per month.

Homeowners insurance:
The cost of homeowners insurance also varies depending on the location of the property, the age of the home, and other factors. As an example, let’s say the annual cost of homeowners insurance is around $1,200. That would amount to $100 per month.

So, the total monthly payment including mortgage payment, property taxes, and homeowners insurance would be around $2,419. Please note that this is just an estimate, and actual costs may vary depending on a variety of factors.
