@Jordan Harrill Waiting is certainly the hardest part, but in this case its the best thing you can do.Id suggest continuing to analyze deals to improve your speed and accuracy.

If you don't know your market well enough to project the ARV with good accuracy, then you are not ready to flip, much less to flip with relatively high financing costs.  

The more places available will give you greater accuracy.

Hi Sean, I wouldn't worry too much about the accuracy of the rental amounts and utility costs just yet.

Hey hope everyone having a good day. Quick question is propstream worth the 97$ just for pulling comps? And how accurate are the comps on propstream. If not worth it what are some better alternative you guys would rec...

And this is why you will find little direction of accuracy on this, there is very few of us at this next elevated level where things leave standard residential and venture into Commercial world where all the rules change, and that is where your at, and most likely why it seems confusing and with lack of information, it is going from one world too another. 

You can have 20% cash on cash for 6 years and year 7 the thing could burn to the ground and your insurance company refuse to pay then your tenants sue you.So the result will only be as good as the accuracy of your assumptions permit, but IRR and the like are important tools to model various scenarios and gauge your risk/return using the information you have today and your best guesses for the future..

Anyone familiar with 78207 zip code could share experience on accuracy of my numbers?

And they all have their pros and cons (price, accuracy, etc.).If you're talking about outbound marketing, where you're texting, calling, sending direct mail, etc., I think you can use pretty much any source. 

TI...aka Tenant Improvements...your future tenant may want to negotiate different terms for the move in, like a few months discounted rent(this could be on top of the above mentioned vacancy) while they build out the place, or some concession for the Tenant Improvements, if you  have an empty shell it could require extensive work to make it business ready for different types of business, think needing to add bathrooms for a gym(dozens of showers and toilets, lockers, etc) or adding a fully equipped commercial kitchen(walk in freezers, special fire suppression, a few extra sinks or drains) With apartments, I rarely have to do extensive build outs or concessions for tenants, even if I have full on renovation, it is almost always replace the old with same but new, ie tear out old kitchen put new kitchen in same place, same plumbing, just new cabinets, and flooring(if you are at all handy, you can do most of it yourself, or be able to estimate accuracy of bids easily).
