One of the things we recommend when purchasing a new home is to have the sewer line checked out. Bad things can happen if there is an issue in the line from the house to the main line at the street. We ask our insurance professional Adam Lauber how insurance may cover an issue if it backs up.
In a competitive market like Denver is right now slanted towards a sellers market there are other ways of winning the bid on multiple offers rather than price. So what if you are 10 or 20,000 over asking and still competing. One way of sweetening the offer is to use your Inspection as leverage. I like to coach my buyers on options and how to look at inspection is one of them. When you are buying a "used" house - not brand new from the builder there are going to be things that need fixing. Some small and maybe some larger items. We usually talk about safety and health items. Maybe its radon or an electrical problems but knowing going in some things will come up on the report. You may considering writing in the offer some language that may set a minimum limit to what you may ask for. Maybe its you won't ask for any items below $1,000 repair value. This may entice the seller to look more at your offer and not get nickel and dime or fixing things after inspection but yet still protect against larger cost items.
