Stair case between third floor and roof need to be strengthened.

A townhouse probably would be a bad plan if it has stairs.

How do you fix that problem of the cement protruding into the house (the first thing I show in the video)?

The latter dictated much larger lot sizes.Some of the towns required raised foundations, or cement slabs with piers or sonar tubing cement supports etc.

They didn't have to dig anything up or backfill and re-cement.

Back in Australia we laid slate floors in a cement base.New tenants...hose them down & re-polish.Like we did for our cement floored pig pens :)

Check out the podcasts when you have time as it will only help cement the great info you'll read here on the forums.

Put cement board and ceramic tile above ,,,not those cheap surrounds.insulate and plastic sheath as necessary.Nothing is water proof, only resistant.

Based on you picture I would pass on that property.Stucco can have problems up front along with the brick veneer.Do not like all the stairs and double ups.Seniors will have a hard time renting and families do not like carrying items up and down all those stairs.That leads to tenant turnover and limited starting renter pool.The parking lot is thrashed.I also do not like the slope of that parking lot.Makes it very hard to pull in and out of there for traffic and makes it hard to get in and out of the car.To overcome all of those things a tenant will have to pay a way below market rent rate to deal with the inconvenience.Is washer and dryer in the units??

I could likely get 750/month.One down side: this would require an exterior stair (at one of the dormers)......so I'd also appreciate your thoughts on such stairs as a safety/ability issue.
