Just wanted to make that disclosure.One can scan these blogs and discussions and find lots of examples of those who are experiencing challenges which could have been avoided thru a modicum of financial and investing education.Some folks post about not being able to get another mortgage because lenders say they already have too many in their own name.Some folks post about needing to find funding for their deals because they lack the resources on their own.Some folks post about deals where the costs have mounted up to a point beyond the profit they calculated from the deal.Some folks post about being overwhelmed by the reporting, accounting and bookkeeping demands of their real estate business.Some folks post about how a deal went sour and they lost a good chunk of change.Now, you can learn how to deal with all of these through the experiences themselves and from the experiences of others.

Double bookkeeping, extra trips to collect, higher turnover, etc.The larger buildings do not pay 10% by the way.

I use three email accounts, property manager, book keeper, and personal.
