It's heavily dependent on the types of properties and the effectiveness your processes and systems.If you don't have systems and processes in place, you may struggle to manage 30 on your own.

I would speak to lawyer and let them review the agreement maybe can do a class action and sue personally the managers if fraud.

@Wiley Hood DIY cost segregation tools like KBKG can be cost-effective for simple properties, but they lack the precision and audit defense of professional studies.

@Hamidou Keita I would recommend if duplexes are limited if you can get a 4-5 bedroom house and either rent by room for house hack or splitting a big house into 2 and adding a kitchenette and separate entrance as a more cost effective ROI option 

Hello everyone! we have several properties now in McHenry County now, and we are looking desperately for an attorney that covers that area. Please recommend someone.
Thank you so much in advance.

Quote from @Scott Tennell: For real estate investors who have worked with private money lenders, what strategies have you found most effective in structuring deals to ensure both parties are protected and the funding process runs smoothly? 

I spent a decade in advertising, before founding and running a custom wood shop for another decade, so 'm pretty good at the self-promotion.I agree with you that the more gorilla approach would be most effective and that's actually what i've been doing – calling RE agents in my service area with active listings, introducing myself to property managers and leasing agents...To answer your question, I will have to handle the work myself for 6-12 months to build out the SOPs and field service management systems, but I have a lot of relationships for those looking to "do the work".I'll check out the meet up and would love to grab a cup of coffee, I'll shoot you an email.

So in effect investors already lost 15-20% of money. 

Direct communication with the builder has been the most effective method in my experience.

Obviously, I'm not a lawyer and should consult with one before.
