It's a good practice to reconcile your book balance with the amortization schedule balance periodically to make sure they're in sync. 

Hello everyone,I’m a 20 year old aspiring multifamily syndicator and I’m looking for someone with who I can practice and role-play pitching deals to with a full presentation and answering tough questions.If anybody could help, would be an absolute honor and very appreciated.Thanks

Written by attorney investors, it's full of practical advice about the management of investment property, has sample forms that can be edited, and - most importantly - tells you what your primary state laws are and where you can read them.

The docs are obviously very important, but if they're willing to share any best practices for screen borrowers, it'll be even more beneficial.

I am a bit new to the real estate investing world and have been practicing underwriting deals.I am looking at value-add deals that may require significant construction (ADU's, garage conversions, etc).  

If those practices don't bother you, I'm not sure what will.

I've delved into approximately 10 books covering multifamily investments, syndication structures and operations, capital raising, underwriting, real estate market dynamics, legal aspects, broker relationships, deal sourcing, taxation, property management, sales techniques, lending practices, and construction processes.

While there are more complicated ways to measure this, the most practical way if you care about answering the question "how much do I make every month" is just income - expenses = cashflow.

That may be the practice of law and opining on their affect by a non-attorney may be the unauthorized practice of law. 

None of the above works unless you take action and put it into practice.
