@James Lindsey, if "house-hacking" gives you the opportunity for FREE accommodation, then as long as the income from the other units covers your loan and maintenance/vacancy expenses, then your cash flow could still be seen as the amount you would otherwise be paying for rent (plus any surplus if any).

So, a lot of the market value is going to depend upon immediate locale.If it's residential zoning and will accommodate two SFR lots, I'd put it on CraigsList at $250k and see if anyone nibbles. 

I'm see you are suggesting 50% might not accommodate the vacancy trend for a certain building or area (along with all the other expenses) and allocating more than 10% might be a good idea.

You should also find inexpensive but effective ways to reinvest and make sure you are offering the best accommodation you can.

(2 more girls) So now we are in the process of moving into a home that properly accommodates the size of our growing family.

We have a lease addendum like yours about entry and asked for a reasonable accommodation request to being present due to mental health disabilities.

You might want to take a look at the Property Tribes website which has useful forums for student accommodation and lots of other topics.

Therefore, I had been eyeing a larger property in Durham that could accommodate 2 couples.  

Any recommendations such as accommodators, things to watch out for eg

If I would have had to evict Im sure my story would have been similar to yours.The tenant I bought out was a head case and would flip from a nice accommodating lady to spewing balls of hate at me and my wife so we limited out contact with her.
