I'll paint oil-based Kilz on any exposed char or smoke damage post demo, add new HVAC and plumbing, do a complete rewire, install 3.5 new baths (only 1.5 are new; others will be re-dos) and a new kitchen. 

I've bought 3 houses in the past 20 months and have an offer in on a 37 unit self storage facility.

But I bet your market is different, and you may have other events, businesses, facilities, or institutions which you can use for long-term rentals.

We are getting gas ran into the property for HE Gas heater instead of oil heat.

Sasan, I have a client in Lawrenceville, GA that developed and owns/operates a very successful assisted living/memory care facility.

Houston's main industry is oil and Gas, shipping,. 

If I can not get access to the property, I will assume anything built before 1982 will contain asbestos/lead in common materials (based on my experience there's a 90% chance this is the case).I believe Texas requires any "contractor" performing ASB abatement to have a license, which means Texas has some regulations established regarding removal & disposal.In California, if you are the property owner you can perform the removal/abatement yourself (assuming SFR), the only requirement is that the asbestos waste be bagged up & taken to a designated facility (in my case in Santa Barbara there is a facility at UCSB where homeowners can take the waste at no/minimal charge). 

If there is not a shared laundry facility that is easy for the tenants to access, then I would suggest adding them to the unit. 

I ran into something similar with a flip that had an oil burner, and the oil soot was circulating in the house due to a bad burner.

BP - My reasons behind writing this post are to track my own progress, get other peoples best practices, and give updates along the way so we can all learn.I am doing my first direct mail campaign focused on self storage facilities in Minnesota.
