I've always enjoyed the idea of getting into real estate and now have some spare change to work with.

I bought a few as spares last year.  

I smashed both parts with an hour to spare.

There are two spare rooms in the house which we don't quite know what to do with, as we don't need any more bedrooms (already has 5 bedrooms).

And because you SHOULD be using your capital sparingly (<30% deposit), anything that grosses less than 1%/m return will be hard to justify buying, simply because: how will it cash flow?

I used base rock (4-6 inches of class 2 base rock compacted at 2-inch lifts), an inch or so of sand, pavers, and a polymer modified sand (which has a little bit of bonding strength) to fill the joints between pavers and prevent weed growth.

But there are houses in the area that pass the 50% rule with room to spare and could (if Kendall Yards succeeds) go way up in property value. 

If you have any spare time give us a review on Yelp and or Facebook. 

It's actually pretty good although it's $10/house so I use it sparingly.

I would go maybe 18% to 20% less in rent,  for the loss of a bedroom.If this guy really want's to make money off renting out a spare room in the house, he'll probably give you a good price to do the egress window.
