for $1,150,000. This 6,000 square foot building was built in 2000 on a lot size of 1.37.
Rare opportunity to acquire a long-term, single-tenant NNN dental office investment located in Oswego's rapidly growing commercial corridor. Positioned on a 1.37 Acre site with high visibility, this all-brick medical asset consists of 3,950 SF of finished dental office space plus an additional 1,950 SF unfinished lower level, totaling approximately 6,000 SF. The 3,950 SF main level was purpose built for efficient patient flow and includes a spacious reception area with vaulted ceilings, 8 operatories with rear delivery and nitrous oxide lines, training/conference room, Dr's Office, lab space, sterilization room, x-ray room, 2 restrooms, and a staff break room. The property has long been occupied by Kendall Pointe Dental, operating under D1 Support, LLC, an affiliated practice within the DecisionOne Dental Partners network. DecisionOne Dental Partners is a growing regional dental support organization with a substantial Illinois footprint, providing investors exposure to an established healthcare operator within the defensive medical office sector. Tenant has been in place since 2016 and recently executed a 5-year lease extension through September 30, 2031, providing investors with reliable cash flow and long-term occupancy stability. Lease structure provides a favorable expense profile with tenant responsibility for real estate taxes, utilities, janitorial, landscaping, snow removal, refuse, HVAC servicing, and interior maintenance obligations. Building has been very well maintained, benefiting from significant recent capital improvements including a new roof installed in 2024 and mechanical system replacements completed in 2023. Positioned near major commuter corridors including US Route 30 and US Route 34, the property benefits from strong suburban demographics, established residential density, and continued population growth throughout Kendall County. Healthcare real estate continues to demonstrate long-term resiliency, making this offering an attractive opportunity for private investors, 1031 exchange buyers, and medical office investors seeking stable tenancy and reduced management intensity.
