Hi there!
Well, honestly speaking, I do not recommend you to go for simultaneous settlement at this point of time. You are in no position to afford that kind of money at the moment and yes, I am talking about a rather huge sum. Not only would you be looking for a buyer for your old place, you would also be searching for a new home. Neither of you seems to have anybody who would like to act as a guarantee for you guys. I would suggest you to go for bridging loan but even that is possible only if you owe 60% or less value of your home. Even in that situation, since you are planning for kids and marriage and unwilling to use up your savings much, I would not advise you to try simultaneous settlement. You may have to sell your current property for less than the desired value and purchase the new one for so much more than it actually costs. Moreover, if you fail to sail your old house in the designated interval of time, you may even end up losing your deposit in the new home. This option only works best for sale between friends or family members. So, I would rather suggest you sell the old home first, rent a place somewhere until your new home gets finalized and then move in. That would be the best for you. Good luck!
