Its not super comprehensive and it does not teach anyone how to do anything specfic it does help those that want to be buy and hold investors how the US TK model works and rentals work in general.. its starter material but foreigners dig it.

Most MI companies have told me they only insure up to 2 units with less than 20% down.The last option I know of that is owner occupied 4 units is VA, but you have to be or been a veteran at one time to obtain this 100% financing option.Features of MCM or my community mortgage:- must have no owned a primary residence for the last 3 years (can have owned rentals or non owners though)- must make under the required area income limits - in OC you can make up to 140% of the area median income (AMI) and each county in the US varies on what you can make- must take a home buyers education course- lowered MI coverage required - this means cheaper mortgage insurance from a buyers perspective- harder to find MI for this loan product (pending/researching)- can finance up to 95% of the purchase price of a 4 unit owner occupied building- can use 75% of gross rents of the other 3 units to help you qualify for the 4 plex purchase which makes it easier to buy

That said, your writing is comprehensible which makes me think your speaking English is pretty good.

I invest in Texas and have excellent "boots-on-the-ground" coverage for property management, agents identifying properties for me, rehab/construction coverage by those who own their own company, etc.  

Do you really neeed an official comprehensive business plan, or would you be just as well served by writing your concept, goal on a big white board for clarity and then writing out the steps needed to implement it?  

Most insurance policies come with 1 million in liability coverage. 

Dwelling, Dwelling Extended coverage, and Dwelling Additional Extended Coverage.

I know some common metrics include employment data, population, avg income, breakdown of neighborhoods etc but I was wondering to get a slightly more comprehensive list.
