Is asking agents to forgo having retail clients too much of a detriment to them?

This is called the investment base, which is the amount the investor will forgo using in another investment by continuing to own the land.

Either way you know what you need to plan for going forward.Best of luck,John

Nothing was flowing into my head until the Billy Holiday song "God Bless The Child" started to play in the background.   

If I were to forgoe the immediate cashflow, assuming rents could increase yearly, the deal should still net a decent 5 yr ROI from the mortgage buy down and appreciation.

If I forgo their increase then it is lost forever- kinda like compounded interest.My other tenants I will not be raising rent on, they are all working.

I'm doing BRRRR's with my 401K money and using the equity from them to pay back the money within 3yrs, so I forgo the regular taxes.

It would have to be a great enough deal that you would forgo rent in that unit for 3-4 months, and probably absorb full damages, and deal with that headache.

If you want to take off exemptions the property has you won't qualify for go to https://www.cookcountyassessor.com/address-search and it will tell you the exact exemption values. 

If you choose to wait to impose the fee in order to mitigate this risk, I would be wary of including prior months in arrears; so you may be forgoing the fee until the month you choose to actually impose it.
