Like replacing remodeling a restaurant you purchase with new interior, grills, fryers and coolers... you are investing in the long term of your business.  

I've seen so many investors in my area start their own meetups... anything from breakfast meetups, lunch at a local restaurant, grilling out/firepit in someone's backyard, etc.

. $95 to be able to grill a hamburger?

And you have to work hard at making the home a destination in and of itself (ex: hot tub, outdoor lighting, heat umbrella, fire pit with wood, grill, sauna, games, arcades, books, great cookware, etc.).

Quick Question:  Do you all allow grills at your SFR rentals? 

We just have a bbq fire pit and a jacuzzi.

Then use Pinterest for ideas on the looks of ideas of fire pits, grills, picnic table(s), games (horseshoes, volleyball, etc)...

Adding some artwork to help give the place more character - $100-200 on Etsy or Society6 can get you some really unique prints that will help your apartments show well in listing pics and really set them apart from the competition.If you have the space outdoors, the quickest and easiest amenities to add are a fire pit and BBQ grill (or maybe a patio as well, if you're so inclined). 

I went to Big Bob Gibson's BBQ last time I was in town. 

BBQ?
