Is your "math" based on the P&L or on what you expected to have from the property? 

For expenses get the current owner's P/L or expense reports. 

They often times are at Loyola in Maywood, or at Rush in Chicago, both of which are easily accessible by the L or the highway. 

He also wants 11 pieces of information ... that all come from my research (like past 3 years of P&L or the business tax returns, etc)So, why do I need an appraisal?

Also, Sch L, line 3 of your 1120S assuming you're required to complete the Sch L or elect to.It might be advisable to re-examine your CPA's comfort level with your current business transactions and evaluate if you need a switch if you've outgrown their practice. 

Don't forget you need plinths in the corners for L or U kitchens (especially for frameless).

@Lor Fara buy the materials needed at places you want, like Home Depot. 

There's likely so much competition at the comps stage that it's commoditized at this point.I would be curious to hear from others, like @Nicholas L. or @Bob Stevens what parts *after* pulling comps they feel could possible be automated without falling into non-scalable traps like iBuyers ran into once they tried scaling their algorithms.

Yes its sad to think that way, but again this is a business and you have to do proper Risk Assessments to be successful.Management rates you should also know for sure...no guessing with that since you should have a good PM Firm on your Investment Team.Recent P&L or tax returns will help you to verify all other expenses IF the property was previously managed.

Even then, I think it's worth it to have an accountant.As for how you keep the books, if you're ever going to care what you P&L or Balance Sheet look like, and when you have WIP at the end of the year, it will be much easier if you're using some piece of accounting software versus using Excel.And again, I use Excel for pretty much everything else...but not for my accounting...
