@Max Bellino For smaller properties like your 2–4 unit multifamily buildings, an online cost segregation study is a quicker and more cost-effective option, providing sufficient accuracy for straightforward properties.

One more reason why people should stop looking for the easy path to building wealth.Increase earnings, reduce expenses, save, and invest.

I just started as a real estate agent and I am looking to build connections with investors.

If  you build your foundation in anything in life illegally is it a firm foundation?

So focus on lead generation.Once you have that covered, then yes you do need to have a bit of insight on the workings of the transaction.But all this should be easy to figure out the moment you keep commonsense in play.Start with getting in touch with a wholesaler-friendly attorney for your closings (if you are in an attorney state), and build a relationship with him (that is also what I did)..He should guide you along the way as you go.

Find someone in the neighborhood of your building to help you out.

Hoping for $325,000 for the build (budgeting for $400,000 with overages).

Looking to rent for $175/night min and total estimate is $100k for the build, aiming for 20% CoC.Any pitfalls/advice for this uncharted territory?

Have the co-op take out a loan for 60% of building value, then charge buyers 20% of value in cash for each unit. 

You can build the tool yourself but it will take time.
