The kitchen cabinets were three different colors, so I knew unifying them would help visually.

Some of the rehab costs were too low (central ac 4k but did not account for duct work), needed a new roof (not included in their rehab estimates), etc.

PLUMBING expansion tanks for hot water heaters, copper scabbed into galvanized pipe and proper venting HVAC - sealed duct work and properly sized for sf.

@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.  

I believe what we will do is use an ultra efficient ducted heat pump system with dual fuel capabilities, so that it will use the heat pump a majority of the time and switch over to using the gas furnace for when it can't keep up.If you have some trusted HVAC subcontractors I would love their contact info.

Only put in popular, neutral and unobtrusive fixtures and colors.

A BIG advantage of these is that we didn't have to fully open walls or run ducting to place heating/Cooling units on both floors.

Mix FOOD color with tap waterb.

Grays, white and blues for colors.
