Can I ask what rate you ultimately decided on and which of those 3 services was closest to that rate?

His post high school plans the last couple of years was to get his real estate agent license, with the ultimate goal of investing.

@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.  

As sales slow, agents look for new ways to make money and survive.

Ultimately, consider your long-term goals and financial stability when making your decision.

The exception is a reverse mortgage which have breach terms that include death of last debtor on title or a surviving spouse.From a practical standpoint, mortgage lenders and their loan servicers are not looking for a reason to accelerate (call loan all due) but may be triggered by poor admin practices of sub-2 buyer.

Start by reading the Ultimate Real Estate Investing Guide: https://www.biggerpockets.com/guides/ultimate-real-estate-investing-guide/introduction2.

So my thought is to provide a summary to sellers of the 3 options on the front end which explain the pros/cons with each and ultimately provide them with an estimate of their proceeds based on the option they select. 

You may want to consider targeting 3-6 months of reserves to cover all your expenses, so you can survive surprises.

This streamlines the defense, reducing legal expenses which the owner (or their insurance company) is ultimately responsible for.
