I have used Cost Segregation Authority many times for my clients with great results. 

No experience with Fairmount, but after a quick web search, they don't look any different than any other DSCR lender... which means they aren't special.Are you working with a broker? 

Though CA authorities keep limiting the interest of such projects, I can still see interest in these projects based on the interconnection queues - still new ones are being added to study despite the increased cost and reduced revenue.You also make a great point regarding < 500kW systems.

I would not add to this post but I would ask for the author to retract their post.

Here are some specific questions i have:1. are there certain locations where revenues may be impacted by seasonal weather changes, like for example heavy rainfall for 1 out of 3-4 months will drop revenue significantly, or excessive heat/cold for seasons will bring significantly less customers?

There are advantages and disadvantages to it and those can vary by the local housing authority that administors the program in your area.

If the costs exceed $5,000, the excess must be amortized over 180 months.

At the time of closing, the Authority will charge you a one-time administration fee of up to 4.99% of the principal amount of the assessment on the Property to cover the costs of administering the Program.

This seems excessive and overpriced, especially since only the front of the building has the water issue.

Consider the potential for increased property value and rental income against the additional management responsibilities and possible tax implications.Remember to consult with local authorities and possibly a real estate attorney to ensure full compliance with all regulations in your specific area.Let me know if you need funding for the rehab.Regards,Jackson
