Proforma vs Current Financials - which do you use?

[Maria Teo]

"For sale' listings provide both current and proforma financial analyses. In a market with rent control, the proforma can be significantly different from current. When considering a building for purchase which numbers do you use?

I always go with current figures because that is what is I can know. Who knows when a tenant will move and I don't want the headache of buying out renters to get the unit to market.

Do the proforma figures warrant any serious consideration and when, or are they just a "come on" to attract buyers?
