QuadPlex in Connecticut determining selling price

[Ken Rich]

I had a question about determining a sale price for a quadplex in Manchester CT. A family member recently passed away and I am the trustee for the trust. I would like to keep the home as I currently have a few rentals myself but I don't want to go into business with family and I live in GA so I don't want to be a long distance landlord. My rentals are all single family so if I were to sell them it is easier to figure out sale price. My realtor has given me a figure that she has come up with but I am not convinced that is the best price.  The issue I am having is that there are really no comps in the area for quadplex. There are single family and duplexes  but what value does the extra apartments add to the value. The house was built 1901 and I will be honest it does need some fixing up. But there are 4 at least 2 bedroom apartments in it. There are 2 that you could call 4 bedroom but 2 of those bedrooms are really small. One of the apartments is vacant but that is just because my family member that passed away lived there. The 3 other apartments have long term tenants in them that create $30k a year. I believe the rents are a bit low bit since I am selling the place I would just leave them were they are. Does anyone know the best way to determine a value of home?
