I have a question for those 'in the know' here.

Our landlords have been pretty deceitful about the house. They lured me in with promises to update and fix things but never did so. Not a big deal for me though since we all knew I'd be here less than a year.

Anyhow, they've put the house on the market and we've given our notice. Fortunately they handwrote on our contract we only need to show the house during certain hours. They've been trying to break that but obviously cannot. So needless to say, they are quite unhappy with us. According to our legal counsel, we're in the right and they are very, very wrong.

So my question is, during the hours in which prospective buyers come in, I get asked questions. How truthful can I be with the answers? The sellers have some major repairs needed on the house i.e. major dryrot, electrical, plumbing, phone, etc...problems and are not disclosing any of it. It's a major fixer upper but they are selling it as a 'normal' house.

Any advice?

No, there is no non-disclosure clause.

I know we've sold two houses and were painfully honest with the prospective buyers even pointing out something the home inspector missed. We just would hope that people would be honest with us when we bought.

The repairs are not run-of-mill repairs. If you lean anything of weight (i.e. ladder) on the side of the house, it'll make indentations in the dryrot. They, however, recently painted the house so the dryrot is not as noticeable now. Add to that the faulty wiring (lights always burn out and go on and off by themselves) and this house is a major fire hazard. We've been told by plumbers that the outside lines are clogged with roots and we have a problem with overflowing toilets. The hot water heater is bad and you can only get about a quarter tub of water before the water runs cool. This is just the tip of the iceberg.

I feel for whomever buys this house. I hope they are smart enough to hire an inspector.
