This all hinges on the property owner allowing you to carryout an inspection in the first place, prior to entering into an agreement. Even if they do, I would think that conducting inspections prior to placing an offer would be a very costly endeavor. For every inspection, what percentage of the time would you not place an offer based on the results? That will be one area where money is completely lost. Next, for the times you do decide to make an offer, how often will those offers be rejected? This is another segment of that upfront investment that will also be lost. If you are concerned about making an offer, then learning of some catastrophic issue that will be a significant expense that affects your offer, that is exactly what an inspection is for. It is informational but also provides the foundation for you to renegotiate based on the findings in order to make your offer financially viable, and if the issues are a bigger headache than you want to address, you can simply pull your offer and move onto the next potential opportunity, minimizing the investment, you have made up to this point. If you are hoping to have a better grasp what the home may require prior to making an offer, ask your agent about any disclosures the seller has made. Also, surround yourself with people who have a great eye to identify items that may require your attention. Do you have a friend, family member or possibly even a contractor that can provide insight and is willing to view the property with you, then by all means, bring them along. You can also begin to learn what certain issues typically cost in the area you are seeking properties. Go to a hardware store and see what certain flooring will cost per square foot when fully installed. Do the same with things like hot water heaters, siding, etc. If the hardware store doesn't provide installation services for certain items, begin to contact electricians, plumbers, roofers and HVAC technicians. This will provide you more comfort when trying to determine what you offer should be based on the condition of the home.
