A good tenant is someone who:Has stable employment in a market segment that is very likely to be stable or improve over timeHas a credit history with which you can evaluate the likelihood that they will performPays all the rent on scheduleTakes care of the propertyDoes not cause problems with neighborsDoes not engage in illegal activities while on the propertyStays for many yearsGood tenants are the exception, not the norm.

It protects the existing structure and the improvements as they are added. 

I joined Bigger Pockets after hearing about it on YouTube and, so far it seems like a pretty good community of people.

My current builder has been not performing on a project I have and it is clear they are not doing anything to change their posture and improve or make up schedule.

First, there is a strong argument to be made against starting with an LLC - look on YouTube for Brandon Turner's video on LLC or not.

What are you willing to "give" that improves the property that may make them happy?

I have some on my Youtube channel, just search

Then does the floor plan and site plan actually improve upon the existing or just make things worse?

We collected cash flow on the property for a few years and did improvements to the property when the leases turned over so we could raise rents.

I'll be curious to see how much rents continue to improve over the next 2-5 years.
