My initial question is… Is it good or bad to have individual septic for each mobile vs one big central unit??

The real loser in the deal was the individual who gave his home way.

It is NOT a 'pay your money, here's your course and see you later' situation.This is a group of likeminded individuals that are all working towards the same goal and are happy to help each other grow and make it too.

I recommend AirDNA subscription for picking and evaluating both markets and individual properties, a little pricy, but if you are taking the investing seriously and with a long-time horizon, definitely worth it in my opinion

We love real estate and love to connect with other like-minded individuals! 

I have a few friends in the area that have moved houses and none of them would recommend the individual or company hired.  

In other words, if one property requires a major repair, reserves from other properties can help cover the expense, reducing the need for each individual property to have a fully stocked reserve at all times.

In those cases, if the HOA assessment is a direct result of the insured loss, it can kick in a specified amount towards the individual HOA members portion of the assessment.  

Any thoughts if an individual property can negative cash flow to provide capital as long as the portfolio is still positive? 

I joined Bigger Pockets in the hopes to connect with like minded individuals who would like to mentor and or just overall help one another so that everyone can be confident and achieve the best possible outcome as we embark on this Journey of investing.
