Yes, but the marketing engine, or time spent with skill building includes a lot of money/time and resources.

Prioritize a reliable booking engine over a complex custom site to avoid technical failures.

I hired an engineered study in order to justify the cost for this specific scenario.

I engaged an environmental engineer for a preliminary report, and found the contamination much more limited than feared.  

I transitioned from the shop floor to business ownership in 2014, launching a successful small engine sales and service company.Transitioning Professional with Mechanical & Business Ownership Background into Real Estate InvestmentWith 20 years of experience as a mechanic and business owner, there is a strong foundation in asset management and operational oversight.

Professionally, I’m a civil and environmental engineer and work as an engineering consultant.

He also severed a roof joist to make way for a sewer vent pipe, which will now require repair (I believe that I will need a structural engineer to sign off on a mitigation plan). 

On the wholesaling front, finding deals is a great skill to have but as others have said, you really need a marketing engine to keep it moving Which also requires capital

Here's what I'd prioritize:1) Engineering-based approach - The IRS prefers studies backed by actual engineering analysis, not just software estimates2) Local market knowledge - Firms familiar with Atlanta construction will be more accurate3) CPA integration - They should work seamlessly with your tax preparer4) Audit defense - Make sure they'll stand behind the study if questionedFor residential properties, you have more options now than a few years ago.

For smaller-to-medium size deals, the more savvy buyers will have a conceptual site plan done by an architect/engineer and will have what we call out here a "pre app" meeting with Planning at the city, to see if there are any initial comments and feedback from Planning (or other city departments) if there are any constraints they see from the out-set that could put downward pressure on the ultimate unit count yield.
