I don't think you are close to the amount of business needed to start shopping for multiunit discounts.

Did great on weekends but even at a 50 to 75% discount during weekdays it was inconsistent. 

Are competitors fully leased or are they offering discounts and specials to attract tenants? 

That said, many MBA programs teach students the skills they'd need to work in commercial real estate such as: Argus training (at a very discounted rate for students), Salesforce, building models and underwriting deals, getting LEED Certified, etc. and they often have student discounts for doing so.

QuickBooks Online Plus will cost your $270 for the first year and second year will be appx $70/month, you get an discount when you pay annually.

And you're offering a discount for the two year with no penalty if they break it after one year, so why would they choose a one-year lease at a higher rate?

Drop the security deposit to one month and advertise second month half off that way you get the entire first month, get a signed lease and it looks attractive to renters because they get a discount.

I have 5 units now and could use cozy.co but plan to add 20 units in 2020 and am considering buildium2) If Buildium offers referral discounts/credits for you, would anyone like to refer me?

And now for the icing on the cake: after the recent Pa Supreme Court decision (Slice of Life vs Hamilton Twp), all of the Townships in the Poconos are in the process of regulating STRs in residentially-zoned areas (limiting # of STRs, imposing length of stay restrictions, imposing annual rental limits, imposing home inspections for STRs, etc, etc)Poconos are great if you don't mind operating in an area with a tremendous over-supply of housing.

I gave a discount based on a 24 month tenancy.
