Can I Get a Mortgage on an Investment Home After Purchase?

mortgage

I’m looking at purchasing an investment home, and it is a small sale which specifies a cash transaction. I plot to pay cash for the property.

I want to have a mortgage on the property to use the cash for other buys.

Is it possible to get a conventional mortgage on a property after buy (I suspect yes), and are the terms generally the same? Is there any major disadvantage to getting a mortgage on a property after buy?
