Probably concrete pipes if no work has been done before.

I was going to go to my first this past Tuesday, but kids were all exhausted.

I also encourage you to listen to all of the BP podcasts as they are a treasure trove of free and lucrative information.My vote is if you can't scrape together more than $5-10K on your own for this idea, then how are you going to fix a broken pipe or a leaky roof that has a tenant in it when it comes time?  

There are openings in the upper west exterior walls where electrical conduit was removed.10.The stucco in these areas has not been repaired to prevent moisture penetration and deterioration.11.The front unit has issues flushing the toilet, which was confirmed with a tenant, so camera scoping of the drain pipes was performed that revealed damages and blockages in the pipes.12.Deferred maintenance on multiple items: cracks around windows and pipes, gas pipes are not supported, pilot lights in heater units were not lit, a water heater unit has no ventilation.I hired a plumber to scope the pipes (please see his report in the invoice attached and photos); a roofing company was hired to assess the damage to the roof above the middle unit only (please see proposed work sheet); a general contractor has inspected the settlement of the wall in the second unit due to the damaged frame.

@David DachteraYes some of the data seems stale sometimes but their "foreclosure" tab has been more exhaustive than any other website that I have found.

plan aborted comma I went to the house and there is too much water damage homeless people have taken out all of the copper pipes there is no tub in the bathroom it is raining where the kitchen used to be from the outside you could not see the Damage Done to the kitchen of this house I'm very upset I took the step daughter with me she was not aware of the damage that was done

Blown-in has advantages but won't touch noisy pipes or creaky floors or loose siding.

It would take many lifetimes to exhaust those REI opps available and on all levels.

And even if I could, it sure seems risky to exhaust the majority of my savings, right?  

Hey guys, I just realized which Marvin I was responding to....he spends too much time on the pipe.
