A study by Neighbors Bank has found that taxes and insurance now make up a significant portion of monthly mortgage payments for many homeowners, with some reports suggesting this amount is around one-fifth of the total payment. The exact percentage varies, with some sources citing 21% and others noting that insurance alone accounts for around 8.5% of housing costs. The rising costs of taxes and insurance appear to be affecting housing affordability, particularly for certain groups such as first-time homeowners in Texas and those in states like Colorado.
