For a minute there I thought Bill Gulley was going to make Tolstoy blush {again} and actually answer your question in-full.

If you do it right, To cut the lip off your roof would be less than the 1500 he wants.

and my contact list who can help me find sellers who want to cash out quickly and not wait until the end of the term of the mortgage note......so I'm learning to start "flapping my lips / gums" and talking to EVERYONE about who THEY know who is owner / seller financing a property and willing to sell their note for cash NOW instead or more cash LATER......

They will be tight lipped on specifics as government actions effect markets and pricing, they won't likely tell you the actual route of a propped highway for example until it is made public, but you can get general growth predictions and data that aid you in your long term planning. :)

At first blush it seems like your capitalization rate is roughly 9% for rents.

It's kind of funny because of all the business owners I know who run consultancies are engineers by training and kind of curl their lip up when they say a smart businessman hires out his marketers and bean counters,haha!

Dirty run off will still get in the gutters with any cover type with holes.Another type has a J type lip, it allows debris to fall further away and water stays on the lip dripping into the gutter, it's fine for light rains, but when you have a heavy rain the water flows faster and won't stick to the lip.

At first blush it appeared the OP was thinking of doing an Angie's list type business.

My plumber says it's better to have overmount, and it has nothing to do with the age of your tenants.I'm also partial to overmount, because a sink with a nice lip looks nice.

I am actually trying to get my tenant rental houses reduced and do more lip stick flips.
