After taking two classes in Python and VBA this semester, I wanted to figure out how I could utilize these languages to make this process more efficient.

I want to work with him but I do not know how to approach the partnership on an official level. 

With the money saved up I was planning to pay a 5% or less down payment of a multi-unit house and rent it to make some passive income while getting the unit paid off at the same time, however, the things that concern me are: One thing I learned with time is that I need to get pre-approved by a lender who will give me an official verdict on my home buying budget which depends on my credit score and income.

There are ways to inspect the property without doing a official inspection. ie: termite and pest inspections 

Although the project went relatively smoothly, there were many challenges including a language barrier and some timing and overlap issues with the contractors.

I've been through this process before not having the write forms with the CORRECT language on the notices and then having to start the process all over! 

As far as management, we represent investors as if they spoke the language fluently.

The fact that he does not have an official website is also concerning.

To clarify, Im looking for one with language with 'Rent back credits" (or perhaps more accurate legal terms)
