Residential Property Valuation

[Wayne Connell]

I am evaluating a residential rental property and the owner, who has a business separate from the rentals, apparently leases a building on the property (not a rental unit), out to himself for an office for his other business, (this building could be rented out as an office so he is not calling it something that its not). This rental amount was included in the valuation on the property as part of the rent rolls.  By my figures the rent amount he charges himself increases the valuation of the of the property by 35 to 40 grand.  Is it normal to rent property to yourself and include it as part of the rent rolls when it comes time to sell?  If not, does anyone have any suggestions on how to handle it with the seller?  Thanks!
