Underwriting expenses and a management company

[Nick B.]

Hello BP,

I recently analyzed a couple of apartment deals and asked two PM companies to estimate expenses on these properties. The numbers were different, of course, so here is the question:

If I use a higher number in my proforma I arrive to a lower offer price, have lesser chance of getting my offer accepted, but then I have a choice of two PMs and potential savings on expenses by selecting a cheaper PM.

If I use a lower expense estimate, I can increase the offer and have a higher chance of winning a deal, but then I only have one PM to work with.

How do I solve this dilemma? 

Thanks

Nick
