Not, hey lets gamble since I love risk with 100k or more, and lets put my personal house, and car etc on line.

First time using this CPA so just double checking that they're accurate.  

They have access to the data accurate data.

I have lots of single-family and 1-4 unit multis that I think it works pretty well for too.But, it's just a general rule and many properties are way lower and many properties are way higher.For instance, I have some office space where the tenants pay for most of the repairs. 20-30% is probably more accurate for that type of property.I have some 'nearly new' duplexes that have very little repairs or maintenance.

Select a company with good reputation for accurate results.

Over the last decade, that gamble paid off and significantly helped grow my net worth and investable cash.  

There is no way, they will know 100% of what you spent your money on.The most important thing for the bookkeeper is that their starting point is accurate. 

There doesn't appear to be much new information on the subject that is accurate. 

The gradings (A-F), are fairly accurate, but not worth the monthly fee.I haven't used the PinPointProfits, but it seems like "+DealDog."

G'Day Matt,You can only do so much with online research.IMO the online stats and demographics often times don't paint the correct picture.This especially tends to be the case for tertiary markets.Finding folks on the ground that "live and breath" the market is your key to success.Those folks on the ground are the one's that bring the "online stats and demographics" to life per se.They will know more accurately what's going on in their local market pretty much on a daily basis.I've always said that you can research online and find a market that has the best growth and cashflow potential.Find a property for a great price and on a great street and in a great area.But if your property manager or contractor are incompetent or cheats.You will loose money.So start with finding the right people first before finding the right market or deal.Just my opinion.Thanks
