It's clear the driveway is shared however we don't have surveys (and we'd both rather not spend the money).

Every year they publish exhaustive surveys of the Best of everything in Dallas. 

Theres a lot on what to do once you have the land but not a lot about doing your due diligence beforehand without spending $1000's in feasibility studies, and surveys etc.My question pertains to Utilities an roads.

I would survey your residence and see if the machines are working well.

Sources: City of Santa Monica, 2016; American Community Survey, 2011-2015 (Table B25064).

A survey was done on the property prior to closing.The reduction in value of the property without the guest house is ~50k-75k.The deal and project is a grand slam with the guest house.

I survey the local laundromats about once a year to see what they charge.

Usually you have an underwriting fee of around 3K, an initial environmental survey will cost at least 1500 (if it goes to a Phase 1 or Phase 2, just stop and find another property) to name a few.Best of luckStephanie

Survey - Do you/they want one and if so, who's paying?

Get an engineering firm to do the survey, and do a plat map of the property with all services and any services required.
