Maybe they know the city/county is buying right-a-way. 

LOTS to talk about in Calgary as quality multi-family deals are being snapped up quickly, multiple offers on handyman specials, and parts of the city is experiencing Sellers Market, while the CIty of Calgary has decided to continue their major capital reinvestment projects, so there will be emerging areas soon! 

I imagine there may be steps to take with the city upfront to determine if in fact the ground on the lot can be built on, but some general guidance or tips on best place to start and what to expect throughout the new construction process in Buffalo.

LTR, MTR and STR work in most larger markets (~top 30-40 cities by pop, or be proximity to metros/attractions/employers).

Baltimore City has a massive vacant housing crisis (no surprise there!).

.- All that being said, you can always negotiate, just be realistic.6) Call the city about the trash.

Agree with Joe, but I'll add that I had a neighbor do this (I am in Union City) and it was an expensive process. 

@Fahima Hilal an architect usually only outlines mechanicals, plumbing & electrical on their blueprints.Your contracts should be creating appropriate drawings showing where their stuff would go and submit to city with their permit application.

For instance my 90 lot subdivision at one point I had 90 legal descriptions and parcels on one master deed.. as I sold them off we just deeded them out separately.. its super common especially in older platted cities were lots might have been small like 25 X 100 and someone bought 3 of them and then built one home on all three.. some places they force merge them others you can go back and recreate the Old lots of record.. there is millions upon millions made by those that know how to find shadow plats and bring to life underlying parcels.

Most "off-market deals" I see in Milwaukee are in the poorest part of the city.
