Trust is a huge issue here because the you have to be able to accept that the information you are receiving is true, factual and pertains to your situation. Hiring and agent to help you is the same thing as choosing a guide that can make your dream come true, and that's what this is all about ... YOUR Dream.
Once you've made the decision to buy a new home, you must understand that in order to buy that home you'll need to sell your home first ... but you're still not comfortable with it, right? Here's what you need to know that can ease the process, you do have options and these options protect you from becoming "homeless" between a sell and buy situation. First, you must 100% commit to sell, when you know you want that dream to come true, if you are ready for life's next chapter and excited to see it happen, only then are you truly ready. Once you've committed to selling, your mind is in the right zone, you can relax because there are two key options that can keep you in your home until you find your dream home.
Contingency: This is an option that allows for you to make the sale of your home valid only when you find your dream home, have it under contract and ultimately purchase that home. These deals require some finesse on your agents part because you do not want to lose the buyer, plus you need to have the contracts written on your sale AND your new home so that they close at nearly the exact same time.
Lease Back: This is an option that allows for you to lease the house back from the new owner for a period of time, as an example, 3 months. This will allow you to continue your home search, having the money available to buy that home when you find it as well as not to have to worry about temporary housing between the sell - buy process. The downside to this option is that the sale price is often quite higher than what you owed, and thus the new owners payments are going to be higher than what you've previously paid. The way the lease back works is that you are obligated to pay every cost associated with that house, it's only fair since the new owner allows you to stay, right? So their mortgage payment is higher, their property tax is higher (because its based on the new sales price) and thus you pay more for the very same house, likely an increase of about 30% more than what your paying now. However, it is important to remember that this is convenient and temporary.
