When you buy a new home you can ask you loan officer to close on the 3rd or 4th of the month and tell him you dont want a mortgage payment until the start of the 2nd month. they’ll roll that payment into the closing costs and can tack onto the balance of the loan.
The reason I like to do this is so that i preserve capital. I like to buy homes that cashflow to begin with and the more money i can keep in the bank the better chance i have of withstanding long periods of vacancy or unforseen expenses.
