Will depend on several factors like the type of property, type of tenants, your risk tolerance, other assets you own, your estate planning, laws where the property is located, etc.

What made you interested in investing in this type of deal?

Not sure what type of attorney to speak with or how to formulate to submit to his insurance.

They are everywhere.A buy box is a tool real estate investors use to determine the types of properties they want to purchase.

Another person with a few million in investments (mostly liquid types like stocks, no mortgages, one paid off rental property and doesn't want to buy anymore property) is make quarterly payments to the IRS. 

A fix n flip type loan may be the "easiest" but a conventional loan will still be cheaper. 

The other risk I see is if there are layoffs of the middle-management ranks or high tech programmer/analyst type jobs move offshore.As you move down the price ranges and even on the higher end price ranges, if they are priced right, they get sold, get sold pretty quickly, and still getting multiple offers.   

These type of loans have the least requirements and are usually approved based on the investment property alone and not the income of the borrower.The highest interest rates will be from a hard money lender.

Hopefully sarcasm comes through in type. 

Depending on your price point, I can direct you to communities and types of homes that would be best suited for you.
