The properties you find should have similar square footage, bedrooms, bathrooms, and be updated to the level you hope to repair the property to.  

You can further filter your search by square footage, which will help tune your results.  

When I calculate that number the square footage of the property of 2100 square x $85 = $178,500.I figure my max offer can be something to the tune of $182,000 with $6,000 back in closing (which is effectively $176k).As far as numbers and factoring in absolute worse case scenario (worst rents possible, property management, and all other expenses) I'm looking at 16% cash on cash return with this purchase price. 

What I've done in the past is I just write a few very basic details about the space on the sign (usually just square footage and number of bedrooms and baths), and a phone number.

You will most likely want a management company to take care of common area maintenance (CAM) like parking lot maintenance, snow plowing and landscaping, which as mentioned above, you will bill to tenants in proportion to the square footage that they occupy.

You are able to input different scopes of work, square footage, etc. and plugin your area code to find the low, average and high prices local contractors typically charge.

I look for exact bed/bath matches and try to get the square footage to be within a 5-10% range.

Just realized an error in my calculation on the square footage...I knew something didn't look right...If I have a total of 120 linear feet on the perimeter (30x30 for easy calculation) of each floor than that's a total of 240 linear feet.

Then we added a lot of value by adding square footage.

Fingers crossed they will allow appraisers to list 1-2 comps of similar SFR with legally permitted ADU close by so we get the same price per sq. foot on the ADU sq. footage as we got on the main SFR home.
