It's also handy for managing income and expenses on multiple properties. 

I am trying to figure out where best to invest, especially since Boston(South End, North End, Southie, etc.) has become so expensive. 

LA is an expensive market to enter. 

If I can't increase the bookings enough to cover the expenses of running the house at least we are going to have to sell it.

Sometimes the most expensive advIse you get will be free advise because it can cost you a great deal of potential money .

It's pretty much only going to be families for a property this large and expensive.

I have a 15k minimum profit on cheaper properties and shoot for a minimum of 20% for more expensive ones. 

What you’re also going to want to take in to account (and I’m not sure these fit into an excel sheet) is the benefit to buying owner-occupied-from loan flexibility and down payments to reduced living expenses and ease of self-management.

In addition to the mortgage, property taxes, and insurance, the projected calculations are taking the following expenses into consideration (5% rate for vacancy, 5% for repairs/maintenance, 5% for CapEx, and 10% for property management; otherwise the income figures would be higher.
