I'm working with the City of Kansas City on determining the highest and best use, which will hopefully lead to building 1-3 new multi-family structures (ideally duplex, triplex, or quadplex).

Not getting at least a title search is off the wall crazy.Land contracts/trusts will work but they are passive trusts and individual liability will continue. 

2 not so nice single family homes and long term rent get a duplex?

Hello BP professionals, I sold my condo in December 2023 and have not been able to find a duplex to purchase in my price range to house hack.

If the tenant identifies an area of moisture that may be causing growth we immediately address the source of the moisture, replace and damage building material (usually dry wall) and or use mold cleaning solutions/mold blocking primers as required. good luck

., "I will buy at least one single-family home, duplex, triplex, or fourplex before the end of 2019") and then do it.

I have a rental in a large lot - easily enough to subdivide to 2 parcels, plus the house sits at the edge of the lot. Does anyone have a rough ballpark $/SF range for new builds?

I think this might be a low point because the Canadian government is trying to pump the housing market before the election next year by lowering rates, relaxing mortgage insurance conditions etc.Yes they have been putting in all these measures to prop up the housing market as they see the pending implosion writing on the wall. 

I've found 2 duplexes in the last year and I haven't even looked all that hard.

And can I get away with only getting permits on new electric & moving plumbing, but demo,  erect walls myself and things like that?
