I've just seen too many unrepped buyers who think they're getting a discount by going directly to the listing agent, but they usually actually leave money on the table or screw up in one way or another without even realizing it (negotiating poorly/ not negotiating at all when they should, paying fees the seller typically pays, missing deadlines, misinterpreting inspection reports, not getting a sewer scope or radon or other things like a meth test or structural report or consulting a lawyer when appropriate, selecting most recent mill levy instead of prorated taxes for last calendar year when taxes went up 30% since last year are just a few examples I've seen personally).

Review with and consult a CPA.

This is a very complicated situation and you will need to consult a commercial mortgage broker (Like myself) Commercial properties have completely different loan terms than residential and are rarely 30 years fixed like your accustom to.

These tools can help you input various cost estimates and projections to arrive at a reasonable operating cost estimate.Professional Consultation: If needed, consult with a real estate accountant or financial advisor who specializes in real estate investments.

I think they are a reliable company, but conditions are very different today. 

Once I move back into the house and get an electrical contractor to consult with I'll know which way to go.

I’m wanting to have consulting and deal structure to protect from heirs, bankruptcy, death, due on sale.

.- Maintaining Property Value: Renting to reliable tenants who pay on time and take care of the property helps maintain its value.

They deal with other clients than you, and would benefit from keeping the business consulting income if you buy it versus going to someone else with a different professional advisor setup.
