Can I approach a (different) bank and ask for a home equity, without disturbing the current mortgage (since I did a quit-claim)?  

Remember that to show the property, they will most likely need to disturb their tenants, also tipping their hand that they are selling - in many cases the tenants do not know.b) It sounds like your particular owner has had a number of offers fall through.

This is a really unfortunate issue and can be quite a disturbance when it comes to responding to the effected family.

I don't think asbestos siding is a big deal unless it's disturbed or removed.

Is there any fine print in the docs that people sign saying they can't be obnoxious or cause a disturbance?

I'm looking to send a 'notice to quit' to a tenant that's been in conflict with lease terms on several different points (unlawful possession of firearms, not maintaining clean unit, disturbing other tenants right to quiet enjoyment of property, etc).

That said I would try to stand the complaining short term because with reno anyone is going to be disturbed and you don't want to start a new market rate tenant under a construction zone if you don't have to. 

My daughter lives there now and she finds this really disturbing.

Let your agent know that you now rent the place and ask if your home owner's policy needs updating.You can prohibit pets, they chew things, bend window blinds, disturb the neighbors and make wet spots if left unattended.

Another disturbing thing is he is also asking for payments beyond the actual progress as per the architect's judgement.
