@Michinori Kaneko I don’t mean this to sound harsh but what you describe is exactly why I teach C.R.A.P (Cash Rich Asset Poor) is not the way to Financial Independence I have too many friends who suffer from CRAP and I am trying to wake them up with this realization all the time

Actually 203k is the option i was going to mention, but i have not experinced the harshness of getting the loan as stated.

Not to sound harsh, but if they have a felony or multiple evictions, they are likely used to getting denied because that's pretty basic criteria.   

Just understand that you’re participating in a practice many scammers use, so you better be ready for some harsh criticism and warnings to prospective borrowers, who have no idea who you are.Label them what you want, but there is no reason for anyup-front fee, in my view.

If it does come out to be a smaller issue you can look into doing your own treatment via some chemicals I can recommend.I'm near a university and I frequently take my literature or correspondence to the tutoring center with some candy and get students to translate it for me.

Most of those chemicals dry pretty fast, and if it was going to peel it probably would have done so already.

But, if someone was poisoned due to chemicals, you would probably be held accountable as the owner.That is why most states require training and liability insurance to obtain a Pest control applicators license.Think about this: If you need to treat a unit and it will require the tenant to be out of the apartment for a couple of hours, you may want to hire a licensed pest control company for the job.

If you do it right, you should not see anymore in a few weeks.With persistence and a thoughtful approach (as opposed to chemical warfare) you can beat cockroaches.

There are 2 treatment methods...the heat treatment and the chemical treatment.

Additionally lot's of particle board was laced with formaldehyde which is a caustic chemical.Formica counter tops are known to have been laced with formaldehyde as well.Acoustical and popcorn ceilings in that circa were known to have asbestos in it which is a highly carcinogenic chemical and can be very detrimental to ones health.Above ceiling and wall insulation was also know to have asbestos in it.A lot of plumbing in those days was made from "Quest" Poly Butylene which proved to be catastrophic and ended up costing Shell Oil huge losses in a class action lawsuit in order to cover court ordered replacement on hundreds of thousands of mobile homes.Finally, once you start going down that road it will be like feeding a cancer that just keeps manifesting itself.
