At the end of the day, though, I'd be paying $100k for a large property (4bd/2ba, 4bd/1ba) or even huge property (if the back 2 units can stay standing) that would be worth $150k conservatively, upwards of $200k based on other sales in the area. 

Barring an unexpected Kasich veto the foreclosure process in Ohio is about to change.Here are a few highlights of the bill: Creates an expedited foreclosure process for vacant and abandoned properties.Adopts the Uniform Law Commission language concerning standing and the ability to sue for foreclosure when the note is lost or destroyed.Establishes that a person is guilty of criminal mischief if he knowingly causes damage to the residential property after being served with a complaint in foreclosure.Modifies how taxes will be prorated in foreclosure cases.Allows, after court approval, the use of private selling officers in foreclosure actions.

The irs lien would attach to the property and remain, regardless of which party had the lien, since they were an owner.  

So, actually your parents owing the entire portion would be much better from tax stand point as entire property gets step -up. 

Most will have language to the effect that you cannot disclose or discuss any data or information that is deemed proprietary to the disclosing party and that which is not generally known to the public.If you want to talk numbers here on BP hypothetically, I think you would be fine since numbers are not "proprietary".

Doing this 5 years ago you missed the Dodd-Frank party, but if you reinstate a new contract you will need to comply with the new financing laws unless you have a specific exemption, you may if that home was your residence and you're in the military.You need a Texas attorney!

This goes from smaller properties managed in-house to larger properties managed by 3rd party management companies. 5.

My experience has shown that if you create win-win situation for all parties involved and you’re transparent in what you’re doing, more often than not, you’ll have a deal.

The best way to avoid any future ugliness is to make sure up front that all parties (including seller and tenants) are crystal clear on the terms:Due Diligence Period (DDP) - I'm sure your contract specifies a period during which you can assess the home and then decide whether you wish to move forward.

The only thing I guess is if you cant sell the home then you head for the hills or you are using that " subject to partner or 3rd party approval "  card trick.You might want to approach sellers from a different angle.
