[quote=plm]I think its too much of a hassle to sell and rent first. Best to save enough for a down payment to not have to sell first. If you can afford higher payments for a move up home, you should be saving quite a bit each month already.[/quote]

It’s not just the down payment – it’s the debt to income ratio. Most folks don’t qualify for 2 simultaneous mortgages where neither property has rental income to offset the mortgage.
