Toxic paint et al.Would you want your family living in house remodeled with cheap Chinese s**t?

However I did note that houses are mostly really old, e.g. 100 years or older... any idea if this poses challenges in things like lead paint presence, outdated wiring, rusty plumbing, etc., or have many of the homes already been updated?   

Learn basic maintenance stuff from YouTube (caulking, painting, learn how to use a drill, etc) and find a well priced handyman for maintenance.

.- It costs me me less to turn over my 1500 SF units that rent for $3k/m then it does the same size section 8 unit because the property is cared for better and experiences less  wear and tear while fixed costs like cleaning and painting are easier to absorb. 

After that it’s paint and finishing touches. the market here has come to a hault.

Paint.

Quote from @Anthony Ng: I just started with them.

My $.02 is that you don't want to paint with a broad brush. 

We didn't know the siding needed to be replaced because it was just recently replaced by the owner before selling it to us, but probably with bad quality paint/siding. 

If you remodeled, added a room, replaced a roof, painted, boosted the curb appeal, etc. that's a different story.
