I keep a portable AC (or 2) in storage at my places and whip them out during emergencies for guests. 

@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 wanted to see if anyone in the Montgomery County, PA area knows any mentors to reach out to?

I'm in the Atlanta area. 

There are a few different options available.

This particular area in our market doesn't have cheaper 3 bedroom 2 bathroom homes so there's a nice sweet spot in the market.

Lenders who call themselves 'Private Lenders" who are actually professional lenders are a dime a dozen.

>ADU's are generally a great return on investmentI could not disagree with this more in southern CA for hands off ADUs added in SF zoned areas.  

Renewing and raising rents up to market rate in the area.

Did you find a CPA, tax strategist in the bay area?
