Sure for most occupant home owners with no money in the stock market and cash tight perhaps (just my views mind you) use of their HELOC to have a house they live in paid off sooner makes perfect sense. 

@Luis Cerwin as others have stated, Nov - Jan is the worst time of year to have a vacancy.Majority of tenants live paycheck-to-paycheck, so all their income goes to Holiday spending starting with Halloween, then Thanksgiving, then xmas, then NYE.January is also historically the worst month for rent payments due to Holiday Hangover Spending.

In this case, you can use Rental Income from the units that you will not be living in and that income can count to help you qualify.FHA rates are going to be lower than conventional for you almost always, but FHA does have a 1.75% funding fee. 

You may also want to consider buying this as a primary and living in it for a year.

I also suspect inflation will drive continued migration to lower cost of living / lower tax states.  

My mum currently lives there, she is 80 and not very well, but you would also become a tenant in common and as such if you had the time you could profit 100% from the transaction, as I need cash urgently and am willing to heavily discount the asset.I am wondering if there is a market out there where someone wants to get a foothold in the London market by buying my part of the property.

My airbnb posting just went live yesterday. 

If I live a busy life and don't have the time or care to invest on my own, but want to put, lets say $200k to work, is a 15% cash flow return reasonable? 

Businesses are “living” organisms with a life of their own, usually having deep meaning to their owners.
