I am taking out a $600k SBA loan on a home staging business. The SBA lender is asking for the following collateral:

Primary residence (asking for $380k lien, value $700k, mortgage remaining $190K)

Investment property (asking for $110k lien, value $470k, mortgage remaining $280k)

Vacant lot (asking for $78k lien, value $500k, mortgage remaining $170k)

Collateralized the entire business assets, worth somewhere between $600k and $1m which they are giving me about $30k credit for (treating rental furniture as "furniture and fixtures" giving me 10% of balance sheet's depreciated value.) Since they are not treating it as "equipment" I don't have the option to get an appraisal, either.

I have a pretty good idea how they will handle primary residence transactions - I'll be able to sell and buy a new house but I'll need to move the lien to the new house.

Can I 1031 exchange the investment property and move the lien to the new property?

Can I give them $78k principal reduction and ask them to release the lien on the vacant lot?

Thank you hivemind :-)
