The "boom-let" in medical office investment properties in the US calls for a few cautions.... Look closely at the cost per SF in the specfic city or state you locate a target medical investment.... Find out if the net lease rate being quoted and signed in current leases is sustainable over term.... Use care now not to overpay in a market area that is peaking or will peak on rental rates within the next ten or less years.... Analyze hospital locations in regard to the investment property -- and how aggressively the hopsital medical building space will be leased over the base terms of inititial leases in the investment subject property.... Just thinking.
