I've been toying with this idea in New England for a few years. I had a rural farm wedding in Vermont and when we were shopping for venues the prices were eye-popping. We very nearly flew to Vegas and eloped! Fortunately my wife had some family friends and we were able to use their land for free. But even then, that free land cost us $10k by the time we rented tent, generator, tables, chairs, dance floor, portable toilets, speakers, got insurance, etc., etc. Later on, I did a trial run with a photobooth business and got to know the wedding space a little bit better.
I think a lot of the naysayers here are coming from places like New England where zoning and neighborhood approval are real hurdles. It is nigh on impossible to convert a money-losing farm to a money-making wedding venue in Mass, VT, or NH. The neighbors don't want noise and traffic. The local officials don't want drunks driving back to distant hotels. The volunteer fire departments are worried about barns designed for livestock holding 200+ partiers. It's a real challenge to pull everything together here, and it can result in a huge investment. You can find incredible farms in Western MA and Southern VT for $500k-$1M, but by the time you get through zoning and permitting and fire safety and septic design and this that and the other, you might have double or triple that invested. All of a sudden $25k for a venue doesn't seem like so much money when you only get 16-24 weeks of rentals a year and you have to pay insurance, staff, maintenance, etc., etc., etc. on top of your PITI. You might as well just buy regular rentals, it will pay the same and have half the headaches.
However, you're in Vegas. It's a completely different world out there. The mindset is 180 degrees from what most of us deal with. You're encouraged to take risks (hey, it's a gambling city), permits are easy, the neighbors mind their own business, and I think you have a real chance of success.
But one thing that is consistent between Vegas and New England is that when you do this you are venturing from pure passive rental real estate to running a business. You are now in the world of Yelp reviews and Instagram posts and super demanding brides who are stressed beyond the breaking point and want to take it out on someone. Not that you can't make a go of it (and make a very nice profit while doing it), but you have to be ready for the crazy time commitments and stress that running a service business entails.
From what I've read, you are ready for the challenge. I think you have a real chance at making this into a nice income stream. But be ready for all the headaches of running an active business, not just a passive real estate venue. Good luck!
