I have calculated a ball park ARV based on Zillow comps and reading my appraisal of the home before remodel and applying methods the appraiser used.

Does anyone have experience with this method, and if so was it profitable for you?

My goal is to start with flips and eventually begin implementing the BRRRR method.

@Jim SpinosaIf you plan to consistently do multiple flips, you will be a dealer, your properties will be inventory, and you will not be able to spread the tax via installment sale method.

One thing I would change is when starting out to do a house hack before marriage/kids/dogs/etc, though a few clients are well along those paths, too.My two favorite clients are both pilots, so house hacking works well for them. 

My favorite show was HGTV's house hunters. 

I have been researching the different financing methods, and would prefer to use portfolio lending for its better rates on my first flip.

Landlord laws are very favorable in this area, you can typically get someone out in 30 days or potentially less with the cash for keys method. 

You already know they're calculating using a method that's not 'honest', so figure out what each unit can bring in with a yearly rental.
