We knocked out the shower and built a hallway and private entrance to the third bedroom and took some space away from the middle bedroom so we could incorporate a full tub and market it as a 3 bedroom now instead of a 2.

Plumbing was updated 2 years ago.Potential for main floor rental and basement rental (separate entrances exist already)Has a natural gas fireplace.Yeah!

I saw the video cameras at the entrances, but thought that he was just concerned or had nicer things, or both.

Can't say I am too happy about the fact that someone decided it would be a good idea to include an entrance on my street(a small and fairly narrow residential street which does not need additional traffic). 

In multi-family is where you have greatest liability - due to others being in same building, and especially if there is a common entrance.

So the question is with the entrance - kitchen floor, it has a patch in the hallway and even if we do not want to, we need to change it in order to be able to sell.

One home we saw is 4,000sq/ft beautiful Victorian style on a few acres with a 900sq/ft in-law suit with all new appliances, hardwood and private entrance. 

Without his help we would lose those advantages.Also my wife and I plan to find a home with a basement and separate entrance that we can rent like an apartment. 

The building is stucco and could use a bit of updating to increase rents but overall is in nice shape and entirely rent-ready.It has:- 3 units (2 2 bdrms, and 1 bdrm) all with their own entrance- The 2 bdrms both have their own laundry facilities- Baseboard heat - Ample parking (6 spots)Based on comparable sales there are 2 sales within the last 6 months within about 1-5km from this location that have sold for the following:Duplex with an illegal 3rd unit, all 3 units are 2 bdrms, gas furnace heat - Sold for 340,000 Duplex - 2 bdrms, - Sold for 290,000kBoth of these buildings look nicer than mine on the exterior but mine does not look awful by any means. 

this may depend on local laws, but he cannot be "forced" out of the house for any reason. as long as he pays rent he has the right to peaceful enjoyment of the property. on the other hand, he cant interfere with the landlords ability to sell, and unless his lease states otherwise he has to allow entrance with proper notice (even for showings). there may be a grey area though if landlord's showing become disruptive to his peaceful enjoyment...i.e. multiple open houses per week and multiple showings would be disruptive to anybodies life.if property goes under contract and current owner gives notice to vacate, it will have to be within the same legal guidelines as any other notice to vacate which must comply with state laws and lease provisions. if he is month to month, that may just mean 30 days notice though. he knew being on a month to month came with that risk.now, if I were him I would tell the landlord to give me cash for keys to be out by end of the month, because empty places show better and he has to move anyway. if he insists on me being out of the house for 4 hours on sat and sun, I would tell him I want to be reimbursed for the two days I do not have peaceful enjoyment of the domicile (2/30*rent payment)he should also start looking for a new rental asapas a side note, why doesn't he make an offer, and save some headache if he is looking now anyway?
