I'd like to chime in on a couple of the common misconceptions that a lot of people here seem to have, both with education in general and with Renatus in particular.First, the concept that Renatus is MLM. 

Are there common roofs?  

Be careful with Camden and Mercer counties, these are commonly found on lists of most at-risk markets in NJ relative to price corrections. 

Some lenders might accept Airbnb/VRBO income reports or bank statements showing rental deposits, but this is less common.

The rent growth rate is assumed to be 2%, which is a common growth rate, and the inflation rate is 5%.

It's also common to encounter retail branch employees who are  not familiar with  the entities and various ownership structures real estate investors utilize since they are normally opening personal bank accounts.

@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.  

Do the tenants typically pay on time or are tenant problems common? 

If you have a $30,000 loss (very common) I don't think a $2,500 difference is going to change whether or not you'll file a claim.  

Real estate investing is forgiving; the average person can still make money even with some big mistakes.Software is a common question on BiggerPockets.
