I think in any market the best way to buy right is to find an area you like and canvas that area with letters, calls and door knocks, getting out and talking to people.

One block from the beach in Ocean Beach, San Diego.

In all major cities, especially ones with a higher crime index, unless you study the market and know it, I would never rely on someone else to choose a block.

Baltimore is very 'block by block' and you can buy what you believe to be a C class property which is actually D-.

Purchase price: $839,000 Cash invested: $83,900Bought an up/down duplex 4 blocks south of Sloan Lake.

Type of construction materials for the build(block/metal frame/wood frame), separate utilities, finishes, tech, cleaning crews, any tips and tricks would be HUGE! 

It wouldn’t even be listed on Airbnb during this period so I wouldn’t get dinged by them for blocking the calendar.

The first warning I always do written (via email), second warning is an official letter on their door saying they're violating their lease to allow other residents the right of enjoyment (if you put this in your lease).

It likely is out of date as to cost as this info is quite old (my guess is 5 years but it could be longer):- Rent Recovery Service: offers flat fee service starting at $20. 3 letters start at $30.

Type of a short letter, deliver it by hand, and move forward.
