Nashville, TN, United States, March 17, 2026 -- The Costigan Group at Compass expands its short-term rental advisory services for Nashville investors, naming founder Jack Costigan as the team's dedicated STR and investment advisor across Davidson and Williamson counties.
The expansion responds to growing demand from out-of-state investors, local homeowners exploring STR conversions, and portfolio buyers seeking data-backed guidance as Nashville's regulatory and competitive conditions grow more complex. The Costigan Group's STR advisory practice applies a pre-acquisition screening process that evaluates zoning eligibility, permit classification, layout efficiency, and conservative revenue projections before clients commit capital.
Nashville operates under a two-tier permit system separating owner-occupied from non-owner-occupied short-term rentals, with non-owner-occupied permits restricted to commercial and mixed-use zoning districts. The Costigan Group's screening process begins with zoning verification through Metro Nashville's parcel viewer and planning department records, filtering out ineligible properties before clients tour or write offers. Occupancy rates across Nashville's core STR corridors have normalized in the low-to-mid 50s, while average daily rates pulled back 15 to 25% from post-COVID peaks. These conditions make conservative underwriting and pre-acquisition due diligence more valuable than at any point in the last four years.
"STRs amplify both good and bad decisions," said Costigan. "If the fundamentals aren't right (zoning, layout, pricing strategy, or location) no amount of marketing or optimism will fix it. We run every deal through a pre-acquisition screen before a client ever writes an offer."
The Costigan Group closed $40 million in transactions last year, bringing total closed volume to approximately $70 million, with year-over-year revenue growth exceeding 141%. The team's STR advisory services include zoning verification, block-level competitive analysis, expense-to-revenue stress testing, HOA and deed restriction review, and conservative cash flow modeling. Investors considering Nashville short-term rentals can access the team's STR strategy and zoning resources.
."Most investors discover zoning issues after they've already committed emotionally to a property," Costigan added. "We reverse that sequence. Zoning comes first, then we evaluate performance potential within the pool of eligible properties."
The advisory expansion comes as Nashville's Metropolitan Council signals more stringent oversight of short-term rental operations while maintaining the city's appeal as a vacation rental destination. The Costigan Group's pre-acquisition framework addresses these conditions by stress-testing deals against current regulatory requirements and projected legislative changes.
