You may have the exact same house 4 blocks away from one you are analyzing, and they have no impact at all on eachother. 

@Brian Ellis you would probably have better luck supporting it with a stud wall instead of trying to incorporate it into the block wall as you already have studs sitting against the interior of the block.

@Nigel FordDetroit is highly location based and prices changes with every handful of blocks. 

Those areas typically wind up being very block by block. 

I would not only not accept the request, I would make sure that all of your posts are set to be for friends only and that your about section is friends only too (not for public) and I would block them.

If yours are higher than everyone else that means you have the best place on the block, which is good for a lot of reasons but could also mean it's hard to replace a current tenant at the same rent when you do a turnover, as there is a chance that most people in the neighborhood can afford your rents.  

There is a way to link calendars in Airbnb where one listing is blocked off if another is booked. 

Philly is challenging since it's one of those cities that literally change from block to block.

Since there's plenty on the BP posts warning investors about Detroit, I thought it would be right to share a few tips for investors still curious or optimistic about the Detroit market.1) First, it's overwhelming how every block is completely different from the next, and just because you spot a good deal on one block doesn't mean that the next block or parallel streets carry the same energy.2) Secondly, you have to think placemaking instead of spot investing due to the excessive vacancies and blight.

Each parcel should have a different lot and block number.
