@Anade DavisHi Anade, You’re on the right track with reaching out to your survey and engineering company—they often have strong connections to local contractors.

My management company has recommended sending in their own contractor to make repairs as the tenant has concerns about mold growth. 

Sounds like you need to have a relationship with a couple of good contractors, 40k for vinyl siding sounds high, what was the material cost.  

Will you require a contractor estimate for the rehab?

Curious if any General Contractors have recently originated commercial general liability insurance and build units that are sold as Condo/PUD's.

Find a contractor to help with repairs estimates or read J Scott’s book on Estimating Rehab Expenses.Good luck getting started!

Any referrals or recommendations for good and qualified brokers, sellers, property management companies, loan brokers, insurance brokers, mortgage brokers, contractors, etc.

This factoring includes the presence of competent contractors who can limit unforeseen surprises and costs.Myth 2: They're Too Risky to Invest InThere is risk in any investment; however, distressed properties are not inherently riskier than any other real estate investment.

What I would like to are some reading recommendations for learning the meat and potatoes on the processes of completing rehabs, and the processes of working with contractors?

When I was doing a house flip in Jurupa Valley, California inland Empire/Riverside and I was looking to do more flips in the inland empire Riverside, and inland Empire areasLooking for some good contacts or contractors or real estate agents who are Flipper friendly?
