Congratulations on your new house
There is nothing wrong with this dryer, designwise. It might need a bit of a tune up if the rollers, the belt and perhaps the rear seal need replacing, but it is a very well designed dryer and there is not much about the good, Whirlpool-made 29" dryers that has changed over the decades so save your money.
The washer will probably last for many more years, too. If you like traditional top loading washers, hang on to the Maytag because you can't buy anything like it now. Often when you move into a new home, there are things you want to do that take money so I would say to save your money by not replacing these until something goes very wrong and even then, you really can't buy a better dryer than what you have.
