Perfect Your Math: Improve your accuracy in due diligence and renovation budgets.

I am considering purchasing a Rentometer Pro account, but would love to hear other thoughts/opinions regarding the accuracy of it.

How close to accurate is Zillows Zestimate in regards to the rent estimate and home price? Anyone know how they get their numbers? 

@Amy Heitner I am sure you had good intentions, but copying inaccurate information from another third-party source and posting it on BP, before verifying the accuracy of the information yourself, is unprofessional and likely illegal.  

Unless you're paying money to a reputable company you're going to have issues with accuracy.

Accuracy on those 2 values is the key to running good numbers.Also presentation is very important.

It is simply an automated valuation tool that cannot possibly determine values with any accuracy.

I will not be doing this deal but am interested in the accuracy of my analysis and any other observations you may have. 

An estimate needs to be made to a certain accuracy.

When it comes to building your own models how do you underwrite value add rent increases ie: bringing rents up to market at lease renewal/ bringing down units onlineIt can be done manually when investing on a small scale but once you get into bigger unit counts it seems inefficient to manually enter the rent roll for each month during reposition and even more complex when there is a diverse unit mixHow you do you model this on your large deals with the goal of accuracy and being conservative?
