How Do I Sell My Home When I Need the Money From The Sale To Make My Next Purchase?

There is no way around it...this isn't always something that is done with ease. Buying a new home and trying to sell your current one at the same time can sometimes feel like being a trapeze artist and trying to catch one rope while letting go of another at the same time. I mean, when you submit an offer for a home, in order to get it accepted, you need to show on paper that you have the money needed for the down payment. So how do you show you have the money ready to go, if you don't have the money ready to go, right?  Because if you need to sell your current home in order to get that money to buy the next home, then how do you go about doing this? And how do you work with the time frame in order to get this done in a good time?
So for starters, let's say the home you are looking to buy is $800k and you plan on putting down $160k for this home. Most all this money you need to make the purchase will be money you will receive from the sale of your current home.So here are a few common options that you can look over when you are in this scenario:

1. Ask a relative or someone you know if you can borrow the money temporarily until your current home sells. While I've seen this before, it may not be common that everyone has someone to turn to for a sizable loan like that. So here are some other choices you can make. 
2. You can make a plan to sell your home, get that money you need, then move into a temporary     living space until you buy your next home. This works for some but can be hard or impossible for others to make a double move and store their things in the meantime.
3. When you put your home up for sale, you may ask for a "rent back" for a specific period of time. This means that a buyer will buy your home, then rent it back to you and you will then be a tenant to the new buyer. For a lot of people, this is a good option. This is something you have to agree at the accepting of a buyer's offer.  Most of the time, this is no longer than a 60 day period of time. So, the catch with this option is that you will have to find a home and have an accepted offer pretty quickly after your current home closes on the sale. Because, don't forget, once your new home purchase accepts your offer, there is a time period of about 30 days (sometimes more) before the new house is yours. And sometimes purchasing a home can have hiccups that can delay the sale or even terminate the transaction in the middle of it. So with this option it will be best to have a good Plan B just in case (such as option #2)
4. When you go to make an offer on the next home, you can make this offer contingent upon the sale of your current home. (which means your offer is only valid when your first home sells) But honestly speaking, we are in a market where it is very likely that the house you want to buy will just go with a more simple offer that doesn't require that waiting period. But if that is not the case, than this may be a good option for you.
