Justin, I'm not based in Vegas so take my questions/thoughts with a grain of salt, but wouldn't it be better to at least give COVID a little bit of time to settle down before making this huge financial decision? You're trying to decide whether to sell or keep your main asset and purchase a new condo in the midst of all of this, with Vegas being one of the hardest hit markets? I just think it's extremely difficult to know how reliable your sales and rent comps are right given the situation.
But assuming the numbers are accurate, I'd recommend selling your house. I think the situation pretty much boils down to.. do you want to take $50k in profit now ($325k - $275k purchase - selling costs) or let that equity ride in the rental. But the problem is that home is likely to be break-even at best.
And I'd agree with everyone else here. That condo doesn't make too much sense, especially with $170/month HOA. That will really hurt you over time.
Best of luck!
