Nothings worse than being in those groups and receiving messages from people who live a million miles away, have a profile page not in English, haven't posted in years, and have no real estate background in their bio let alone any of the posts. 

@Scott Mac Tribal knowledge in the field of aviation refers to any information you may have that is not common knowledge.

I was first stationed in Virginia and did 9 deployments all over the Caribbean, Gulf of Mexico, Atlantic, and Pacific on a 270' Cutter for 2.5 years doing drug and migrant interdiction. 6 months of aviation maintenance school followed and afterwards, I transferred to my first and final aviation unit in Cape Cod, MA on H60 Jayhawk Helicopters.

This can say a lot about a company.do they speak intelligible English you mean ? 

Working for investors and getting repeat business makes great sense for this kind of contractor, because he may not be interested in doing the kind of marketing it takes to be really successful working for homeowners.His English may be somewhat rough...but it needs to be good enough that you don't have a language barrier separating you.He may be newer in the business - recently out on his own, after working for someone else for awhile.He honestly may not have all his processes and procedures worked out, so you may have to be more understanding of that.But he can show you good quality work, and multiple references that will attest he's not going to take your money and run.

I work in the aviation business as a dispatcher and my wife works as a nurse practicioner....

I am using English like folks in the street and as a specific technical terms.Many folks think about building equity through a process of holding long term where each monthly payment reduces the loan.

@Jarrod English I agree with @Jon K.

I wrote this first thing in the morning (luckily im not an English teacher) - that's my story and sticking to it, thank you for the correction, that relates perfectly to my topic ( have to say I'm a bit embarrassed), but thank you nevertheless.Thank you for everyone's advice on the topic, and I have been approaching buyers in a very non-grandiose manner.
