Some grow too fast and discover they've built a full-time job for themselves.Growth can also include improving cash flow, increasing property value, or optimizing operations.

So far the concerns I have discovered would be things like control of collateral, maintenance requirements/margin calls, and various fees that may be charged on quarterly or annual basis.

If there's a second call for the same issue we have the line camera'd to verify the line is in good shape and that it is clear going forward, and charge the tenant if the clog was their fault but do not charge if we discover a mechanical defect; we fix the defect. 

Most of that is not really worth much to most people. 

If any of your properties are discovered by City officials to be unregistered, you can receive an administrative citation for failure to register; this penalty can cost $100 or more per property.

That's not a guarantee - some of those people may be breaking the law too - but it gives you a good idea where to start. 

With enough knowledge you can make a educated decision on which approach you take.My experience:I personally don't sign up for any program who take you aside during events and try to sell packages that is just blatant sales strategy.Once you sign up there is every attempt to make you sign for their programs for bookkeeping, registered agent, LLC or corp setup fee which have ridiculous even with platinum membership.Basic standard structure they suggest to take advantage of multiple deductions can be easily achieved by proper education or work with a good firm like https://wcginc.com  who is local to you.A umbrella C-crop to manage all other LLC properties and take advantage of many tax deductions that are not available with a llc, its also used to take losses up to 100K as startup expenses and dissolve the entity after few years.Few LLC entities for investing in Real Estate, etc preferably in Wyoming or Nevada ( you can find many companies online who can do this for $150 compared to anderson $1500-$3000) , they will claim they have a secret Operating agreement which is bogus.They certainly try to take advantage of tax loopholes and claim to be smart people, my view they are just taking advantage of numbers as per their own statements.

,We discovered over the course of this discussion that more smaller extra payments produces less benefit than fewer, larger "chunks". 

If you discover one that sounds potentially relevant, and you have not explored it - see if you can still get hold of your accountant to ask.

People reinstate the loans and do loan modifications all the time.
