Find out if there is a wall with convenient access to plumbing drains. and if that area could work as a kitchen.

You may have to give up a big % of the GP on your first deal just to be a fly on the wall while building a track record. 

Really don't want pet-pissed walls at my houses. 

I think the best you can do is add a few accent walls in the bedrooms and make it less neutral. we paint everything white in our new builds and very neutral as well as do higher end simple painted accent walls and trim walls to help make the house a little different. if you really want to sell I'd get a interior designer / stager and spend 5k with a way more experience agent who sells new builds. we are licensed if you can't find someone. the way I market is very different. 

I feel like I need this printed as a creed on my office wall. 

@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.  

So, agree with @Nathan Gesner about letting the tenant prove there is unhealthy mold issue.Will point out though, that there is probably mold behind the shower tile walls.

Didn't move any exterior walls and added more value through converting from a 2 bed/2 bath to a 3 bed/2 bath. 

Lease violationsTell the boyfriend you might have to patch some holes in walls and doors or clean up from a homicide Call police during the activities for a welfare check Ask her what’s up ?

Sometimes, I see people add bedrooms when it doesn't make sense.It's often not as simple as just putting up a wall because you need lights, outlets, and proper ventilation.
