., Is this simply the average cost per square foot to build in the specific area I am looking to invest multiplied by the total square feet of the multifamily building?

I figured but wanted to make sure so I could respond with my best foot forward.

When it comes to pricing structure; the rent per square foot, price per square foot, and property appreciation are relatively uniform across the individual submarkets so if you wanted to calculate or even model out potential rental yield it shouldn't be a large hassle. 

To start you need to fix the water issue, check your gutters, check the grade of the area, possibly need to excavate seal and install new footing drains.

@S Buhidma CaudillPrices on the high side can range from $150 to $200 per foot to replace a sewer line.

I feel the first appraisal is a more accurate reflection because the price per square foot ($115/sqft) calculated is more in line with what I see on the market as opposed to the $102/sqft in the second report.

You may be thinking you know how much a tile install costs because you looked at Home Depot and tile is $4.99per square foot...so, simple multiply that by square footage.

or maybe even just with getting your foot in the door with major RE companies?

Have them use the following factors to determine whether you have a comp or not: age of subject (within 20 years down & up), style of subject (try to identify the approximate baseline per sq foot sales value of each style), square footage (within 200 square feet up & down), number of bedrooms (if subject has 3, you have to look at 3 or more; less than 3 bedrooms are typically less valuable because they appeal to single people instead of families), number of baths (1 is bad & you need to compare to properties that only have 1, 1.5 is less bad, 2 is good, anything more than 2 is good), parking (off street vs. on street & garage vs. no garage)2.
