You have full access to see what similar homes with similar finish outs of your final product are selling for to back into an accurate ARV.4) Lastly, as someone who has house hacked myself I would make sure you understand how a lender will analyze your second property.

For newly constructed, purchased or renovated properties and also retroactive generally over the last 10 years, building components are properly classified into individual units of property and accurate recovery periods for computing depreciation deductions.

Everything people read on BP should be taken like a grain of salt and do reach out to experts and get the real answer for their scenario to make sure they get the most accurate solution.

Take a look at all the actual numbers because my suspicion is your underwriting may not be accurate, just from knowing how hard it is to find properties that pencil out these days in general, and from seeing how many beginners are underwriting their deals... 

i believe that you mentioned in another post that you don't already own a primary residence. is that accurate? 

a good deal for a SFH flip would be the buyer being ALL IN at absolute max 80% of the ARV (including the PP, renovations, assignment fee, closing costs), but a lot of investors would say it has to be max 75%, 70%, maybe even 65%. that said, shoot for 65%, and know your renovation costs. i've used $65/sqft for a gut reno, and until proven otherwise i'm assuming it's a gut job, BUT that PPSF is not always accurate, sometimes there are unique issues with the property that would drive that number way up. it gives you a place to start, though. 

A local real estate agent with knowledge of multifamily homes in the region should be consulted.Check that the rent reported for the inhabited side is accurate.

My question is should I have a contractor review the property/or send photos and videos to get a more accurate number on renovation cost and then afterwards take that to the seller and negotiate?

Lot of people may leave the industry.Carlos, the most accurate comparison I can think of for this is Y2K, seriously. 

I am exhausted.I went ahead an sent in $5k since I do know that I owe something and I'll pay whatever is left one we can actually figure out an accurate number.
