And the structure cannot be an older style with under-sized studs, beams, headers, etc. 

Collecting the rent 1930's style.

Hi Alex,I design and style Airbnb's.  

Examples would be incorrect square footage, incorrect year built, incorrect style of home or materials.  

This all goes back to attachment styles and my business partner is hung up on that.

I prefer durability and simplicity over style. 

As you progress, you'll discover strategies that resonate with you and your investment style.

I’d study competing units to see what they offer and think about a style and amenities that will make you competitive.

@Robert Rixer, I don't know how creative these are, as many are common plays:Valet TrashFencing in first floor yardsProviding washer and dryers for added rentReserved, Covered parkingTech PackagesInternet and Cable contracts, with reimbursementsPayment Plan rents, with small service charge (i.e. bill 1/4 rent each week)Reserved Rental cabanas at poolPrivate pool party rental optionGolf Simulator in clubhouse - fee basedOn site, self serve car wash (quarter feeder style)Charged group fitness/personal training servicesGame room in clubhouse with monthly subscription for tenants (Xbox, Playstation, etc)Changing out high maintenance grass for astro turf or lower maintenance/lower water use shrubberyBut ultimately, I think a lot of NOI increases come from deep dive into understanding EVERY expense and finding ways to minimize them, and/or no outsource them.Train maintenance team on basic HVAC and appliance repairs (find way to get them licensed as needed)Buy paint sprayers for faster, easier turns versus having to hire a contract painter, and possibly repaint whole unit each timeStandardize all finishes, so you can buy in bulk, everything from hinges and door knobs to cabinets, paint colors, and light fixtures.Potentially get leasing people onto lower base salary with higher bonus potentialBulk/bundled insurance across portfolio (even better at scale is to self insure)Regularly test sprinkler systems for leaks.Non-NOI, but benefit to you: partner with insurance agency to get referral kickbacks from your tenant base for renter insurance.  

Not sure how much that tells you, but might be better than nothing. also depends on the type of property if its a rental being sold then ya most realtors will have a good list of folks looking for a rental with teh right numbers if its owner occ this simply is not remotely possible unless its a certain school district or certain style of home..
