I hired a contractor who left his workers unsupervised, they painted the whole house but did a terrible job because the paint didn’t stick.

Research the paint, floors, etc.

It was a tenant with a couple unauthorized cats that sprayed everywhere and we spent $9,000 on cleaning, flooring, and paint. 

Painting in the interior saved at least $4k.

I plan to do the trim flooring and painting myself and hire the rest out. 

Paint, floors, bathrooms, general maintenance, landscaping What was the outcome?

One thing I am hearing is I need to be Lead Based Paint certified, even if only the contractor does all the work.

Paint, floors, bathrooms, general maintenance, landscaping What was the outcome?

I’m not super keen on having long-term tenants in a single-family home in California, but I’m open to advice on that.The house is in decent shape but could use new flooring, a paint job, and potentially heating and/or central AC, as well as blocking/taking out the existing fireplaces (don't love the idea of fireplaces in a rental). 

For example my simple spruce up would be, renno bathroom, and kitchen, paint, and redo carpet upstairs.But if i think real deep into what I could do to make it a STUNNER then I think, knock down walls, create more open/broken floor plan, add central air, possibly do an addition to add a 3rd bedroom and second bath.So when you could do ANYTHING .. how do you draw the line of what you should do?
