+ I need more practice/guidance on accurately estimating repair costs+ a checklist for what to do to thoroughly evaluate a wholesale deal before making an offer

The Zestimate on Zillow is sometimes very accurate and sometimes way off, so it's not very reliable on its own.

It is quite accurate and will show traces down to .1% of the original virus which is much less than can infect a person.Frankly, I think things are a bit overblown.

Though the tax records are not 100% accurate on this subject, they are about 90-95% right, so this property is likely an illegal multifamily.

On remainder, I'm looking for CapEx stuff like roofs, siding, windows, paving and ANYTHING that involves moisture invasion.3) Books/records (30 days after M/A) - Look at the ACTUAL (do NOT accept ProForma from a broker as final) to see if the NOI is as promised and the rent roll is accurate and you have all the tenant docs like leases at a min. 

Important to keep in mind both scenarios are accurate, the former is typical over time but the latter is a better yearly expectation with stable tenants.  

@Joshua Hataway Yes a property manager should be able to give you an accurate number for rents in the area.

@Joshua Hataway if you are trying to get the most accurate picture I would remove the management costs during your rehab time, unless you are performing the rehab while tenants are in place.  

Is that accurate? 

I get calls from buyers wanting stuff, I spend time finding them things and then they vanish.Also as a buyer you can usually (do NOT sign a Buyer Agency) pick any agent you want.Having said all that, sometimes 30 minutes is a quick turnaround especially if you're asking for info they have to get together and make sure its accurate.
