For SBA lenders
Short answer
The same level of environmental due diligence (typically a Phase I Environmental Site Assessment) is required for all real estate collateral, regardless of whether it is primary or secondary collateral for the 7(a) loan.
SBA policy mandates environmental due diligence on all real estate collateral for 7(a) loans, to protect against potential environmental liability that could impact the value of the collateral and the lender's ability to recover. This applies equally to primary and secondary collateral positions.
A $1.5M business acquisition loan is primarily secured by business assets, but also includes the owner's unencumbered personal residence (valued at $500,000) as secondary collateral. The lender must obtain a Phase I Environmental Site Assessment for the personal residence, just as they would for any commercial real estate collateral, to identify potential environmental risks.
Insider move
Lenders must ensure compliance with environmental policy to avoid future liability and protect collateral value. Neglecting environmental due diligence on secondary real estate collateral can lead to a guaranty repair or denial if contamination is later discovered, impacting the loan's recovery.
