Attorney says they can only take a percentage of ins check, not all that is owed to them.

You can find an agent who knows about investing, but you have to seek out agent(s) with that knowledge, a small percentage of them have it.As far as property management, I recommend you read "The ABCs of Property Management" by Ken McElroy to get a good overview of things to consider in your decision to self manage or hire a PM. 

The percentage of Americans that own pets is striking.  

So many variables with this one.

We personally stretch ourself thin to do deal but I have a financial background with high incomes and no incomes and other variable.

You can see much more general "trends" that might give you some guidance, but the reality is that there are huge variables that can shift a trend graph fairly quickly. 

I've heard other investors talk about 6%, either variable or only fixed for 5 year then adjustable.I'm willing to pay the 1/2 % higher to get the 80% LTV and fixed for either 15 or 30 years with no balloon.

Anything to add protection and slow down a legal attack.Alot depends on the state, in SC a single member LLC is treated as a sole proprietorship and not granted the legal protections of a LLC, but a multi-member LLC (ownership percentage is not dictated) are granted full protections.This is why I said go talk to lawyer.  

@Matt Kvalheim I like your thinking in upping the maintenance and vacancy percentages.

I've thought about constructing one entity and selling ownership in it proportional to the percentage / amount any one or each ‘partner’ desires to participate in the deal.
