I found their numbers are accurate and their prices are a little high. 

Speak to your lender/broker for a closing costs estimate, which will be much more accurate than a percentage range. 

If the software is not simplifying your life or making you more accurate, you shouldn't use it.

Much more accurate & protective than a general number.

I would also want to verify that the renovation budget is accurate. 

Once you find a house that you believe would be a good rental, meaning desirable to your target market of customers (people within a couple of mile radius of the place), and all of the costs of monthly ownership that you can accurately project fall below the rental amounts that you project that you can get from your target customers, then you have a possible business asset that you can use to produce income, and have renters pay down the mortgage, while hopefully it goes up in value at least with the rest of the economy. 

If they are there, then their numbers are accurate except for cash on the side. 

By all my research and estimates, the pro forma is pretty accurate.

The following year would be considered passive, so even if you materially participated, it would still be passive the following year and you cannot offset your W2.Is this accurate? 

Which is not true and riskier to only gamble on appreciation I think.
