Once you build a model you like that uses sources you trust and appears to align with reality maintaining it is simple.Also, if it really does match the observed reality (or comes close) you can use it to predict, at least generally, enough to include the data at some weight in your decisions, which van increase your confidence.And i promise this is the last word from me - historical (even 2 months ago) data is pretty available since few care after the sale what it sold for.

@Boots Bonner what model Toto do you use?

The guy who is cleaning floor from carpet removal is getting $15/h.Waiting for technician to come to check, for appliances delivery etc is a job, too.

For the above project, we're anticipating ARV to be between $850-$950k and frankly, the deal wouldn't really fit our investor's needs or our model if not.Any thoughts here?

@John Paul Whaley With the BRRRR model, the amount that you can refinance is subject to what the bank is willing to approve.

How will you manage your delivery cost?

Please correct me if I'm wrong.If that is somewhat close, your model lives and dies by interest rates. 

You should be focusing that energy on getting your new listing up, making sure supplies are ready and really trying to figure out how your rental model is going to be better than the previous owners.

Its all about testing out all of the models that interest you and landing the one that makes the most sense for you and the goals you're aiming for.Best of luck to you moving forward!
