3 questions to answer before you sign on a parcel
1
Where are the nearest utility stubs?
Call the utility provider with the parcel number before you make any offer.
2
Has a perc test been done?
Failed soil means engineered septic. That alone can add $25,000+ to your project.
3
Can a crane and a semi get clean access?
Tight clearances can kill a standard modular drop or add significant cost to work around.
Estimates are ballpark ranges based on national averages for STR parcels. Actual costs vary by region, contractor, and site-specific conditions. Always get at least 3 quotes before committing to a project.
