I wholeheartedly disagree. There are lots of 75K homes here in Utah and in Salt Lake City specifically.
If you are looking for stuff in the 75K range, you'll find them in the Hoffman Heights and Rose Park neighborhoods of Salt Lake City. These neighborhoods are safe, decent but working class.
Another example is a wholesale deal that got sent to me today that's in Salt Lake City (but not the neighborhoods above). It's located around 1100 south and 100 east. It's under contract for 55,000 and needs 20K in repairs. All said and done you could sell it for 100K or rent it for about 900/month.
I would avoid St. George because of the lack of economic activity. Yes, lots of snowbirds and tourists but it's not like SLC (and the rest of the Wasatch Front) where there is a diversified economic engine to keep rentals full (there's a reason why large apartment complexes are SELLING at a 6.5 cap or less here).
So as a former Californian, I'd say yes, come invest here. I have. It's been a great decision to be here. And yes, the Mormon influence is "different" but I've never had more respectful, hardworking and trustworthy tenants.
