I would strongly agree that holding off on your downtown purchase is the way to go. I think you could see exceptional deals downtown in the upcoming years. I think that location may be the single most saturated location in the county.
Also you may want to decouple the sale of your current condo.
Maybe you sell the condo now and then put the money in a CD or something and let it accrue interest. Or maybe go live downtown and rent out the north park condo. Run a quick spreadsheet to see if you can get a positive cash flow out of it.
Or if those alternatives don’t work then sit tight.
Remember any decision that leaves you stressed out is the wrong way to go.
