Or what if some moronic narcissistic imbecile decides to blow up the planet, now that that ability has been concentrated into the small hands of so few? 

I've seen numbers in the 14% to 16% range.As far as improvements, I'd concentrate on whatever it takes to get the home to the point that it survives an FHA/VA/USDA appraisal. 

The agent told me to “just make one up... find a form on the internet and fill it in”.

Go to your local REIA meetings and connect with them on the Internet using BiggerPockets, Craigslist, Facebook Groups, etc.

Congratulations, you have found one of the most valuable free resources on the internet for real estate investors new and old, Quincy. 

Also if the complex has an investor concentration of more than 50%, it becomes non warrantable, again limiting your number of available lenders.  

I always taped my bedroom door at the bottom when I would leave after going in there and exterminating :). that was the concentrated area so it was the no-go zone for a while.

There is not much on the internet about this subject except on here.Did i miss anything?

You learn to be professional and not laugh early on, when you're working with brand new real estate agents who refer 'clients' to you who have no income, no credit, and no savings, but are dead serious that they want to buy a $1.5m house in San Jose oh and by the way they also want the lowest interest rate they can find advertised on the shadiest corner of the internet. 

The home after all would be getting paid for by the rent at least.I am interested in feedback and I have a lot of questions, several that I cant seem to find an answer for in books or internet.
