I just finished 78 acre 50% agricultural & 50% wooded/wet areas, with one existing 6,880 SF pole barn and a proposed 8,800 SF wedding venue pole building. The existing pole building was a typical agricultural building, with a concrete floor, exposed framing, minimum electrical and no plumbing. One 10' overhead door and a 16' sliding door on each end. The proposed building was going to have an approximately 6,000 SF 14' high eaves reception hall, with no HVAC (in northern Michigan), no insulation and with the exposed framing being painted white. On each side plans called for about 1,400 SF additions that would have HVAC, plumbing, insulation, etc. One side was going to be the bride and party ready area, which was going to be mostly open with an enclosed private bath and shower. The other side was going to be two multiple stall bathrooms, a prep kitchen and a storage room. They were adding some fancy glass overhead garage doors to allow in some natural light and to open up the facility.
I ended up using all three approaches. The contractors estimate to construct the new building was $1,200,000 +/-, while my cost estimate for the new building was about $800,000, to which I added the land value and the depreciated value of the existing building. For the sales approach I had fairly good information, from another recently completed report, as to the contributory value of second and third pole barns on the same site. I then valued the acreage along with the existing pole barn based on comparable sales, then added the estimated contributory value of the proposed building. The Income was really wacky, the property owner told me and provided myself and the lender with her income and expense projections. I was a bit skeptical to start and as I researched typical rental fees for similar type wedding venues, I found her projections were more than 3 to 4+x's what others were charging. I was fortunate in my research of wedding venue rental charges as one of the people I cold called and explained what I was doing offered to send me a copy of a price/service survey he had conducted in May. Altogether he provided me with information regarding 30 separate venues.
I ended up providing the lender with a range of value which had a nearly $800,000 spread. I told them if they want to use cost as their loan basis fine and if they want to use market that is fine also. From an income standpoint, I told them most of the projected income value would be attributed to the business and personal property. Based on my market research regarding income potential and the projected expense the income value was under $200,000.
Kind of like the old story that asks how does a mouse eat an elephant? One bite at a time.
