The only rent abatement or credit that is somewhat normal is when a home sells and the park offers concessions such as a free month or months lot rent or discounted rent for a period of time for a faster lease up.

I am very new to the REI community but as a market investor, I can for sure tell you that if this scenario could be discounted, it is definitely worth the reward in the long run.

Does anyone have an ap or software that they use for fix and flip?

While I agree 100% that taxes, insurance and other upkeep are expensive, if I rented I'd be paying a landlord a sufficient rent to more then cover these amounts in nearly every instance, plus his mortgage principal amortization.Since, personally, I prefer a home that is nicer then most rentals and like the idea that the home is mine to do as I please, I choose to own.As a RE investor, with over a 150 paid off doors, (antithetical to you Joe, I'm aware) I know how to purchase RE at a discount.

It took me a while to recall that they like to bury all of their information in PDFs or web accessible software.  

I will check if the local theater has a quantity value discount.

What software is everyone using to track their revenue/expenses and to easily determine KPI's?

The ENTIRE COURSE, including 21 books, agreement software and market value calculator costs under $100, and includes FREE coaching for life.

I had a client do an ADU construction on site and he just discounted the lease for the construction period and they were good!

If you want them on a lease make the difference meaningful on the discount for a lease, more than the $25 per month you are asking.
