Hi Melissa Harris -
I find my comps on mls and look at valuation two ways.
1. How does the building comp out to other similar buildings? In Boston there are typically pretty decent comps although sometimes you have to look in different neighborhoods from a location standpoint but have similar demographics and rental cost. For example, this part of Roxbury (Fort Point) would comp to Mission Hill and JP but not further south and east towards Dorchester as it is further from the T and rent is less.
2. The other valuation metric I use is to see what the building would be values at if I sold each unit as a condo. To get to that value I look at condos in the area mentioned above.
Regarding how I get the appraiser to my number (which is typically reasonable and based in fact) is by doing a few things.
A. ALways be there at the appraisal and pitch to the appraiser what value you think it should be and why. Casually bring up that value as many times as possible while you walk the home with them. Walk them brought your valuation methodology.
B. Give the appraiser a spread sheet with the comps you think are comparable and how those comps and the map to your valuation. Again- the more the appraiser sees the valuation you are looking for and that it is supported in fact, the better
I also like to follow up with a call/text/email stating the valuation you think it's worth and to offer to have a discussion if he isn't getting to that number. Valuation is very subjective and the same data could produce valuations that are 20-30% apart. In other words, the data could support both a 1.5 mil valuation and a 1.8 mil valuation. As the owner/developer you want to put the birdie in the appraisers ear that they should be on the high end of that range.
