However, I have minor construction experience via diy projects my family would do around the house (finished the basement, backyard patio and fireplace, bball court, stone walls etc.).

I really appreciate it.I'm glad Im not the only one to mess up like this although it sounds like I set a record for the scale of the screw up with so many messed up letters before I caught the mistake.Anyone need any kindling for their fireplace? 

Can you tell me how a fireplace effects your local market in pulling comps or how to adjust the valuation?

We have a duplex that sits on top of garages for each unit, and then has a detached 2-car garage with its own power/meter, and even a fireplace, and they're all rented separately.

If there is a fireplace, we look into the firebox too to make sure they are not burning prohibited materials and that they are keeping the firebox clear of ashes.When entering a room, we look around in a clockwise manner and down/up too.

There is a natural fire place in the first floor unit. 

hey guys,I'm under contract w/ this house and know exactly what I'm going to do with every room already to flip it, but this fireplace is giving me an issue.

half assed comp analysis, but if you want something to start with...PropertyTypeBr / BaGLASoldPriceNotesAdjustmentPost-adjustmentsubjectsfr2/11130123 main stsfr2/1unk1/25/2016$595,000.00huge new kitchen, orig hardwood, fireplace, dumb agent-$25,000.00$570,000456 wall stsfr2/197211/30/2015$525,000.00granny house garbage condition possible flip$20,000.00$545,0001031 exchange avesfr2/19143/15/2016$485,000.00.$485,000321 123rd stsfr2/110404/8/2016$475,000.00really good condition -$15,000.00$460,000And, again, this is for refis.

And for him to remediate the asbestos (it's in two fireplaces and a tile floor in basement).  

LOL, if you don't have a calculator to use in RE deals and you only look for deals as obvious as Rob's car example,you won't be making much money or be around long.While you may understand the terms, you need to study the basics and understand the comparable property valuation process, you don't need to be an appraiser and add values for a fireplace, but understand the valuation of the overall market, neighborhood influences, location, how a school influences price and conditions.
