First, you might want to save up for a sizeable down payment so you can pay a huge amount upfront and thereby reduce your monthly fees. Before obtaining any sort of financing, be sure to understand how mortgage works. Likewise, find a reliable mortgage lender that can offer reasonable rates.
Meanwhile, keep in mind that aside from the home’s market value, you’ll need to shoulder a bunch of additional charges that come along with the purchase. Be prepared to pay for services like property surveying, land registration, and local authority searches. It's also possible that the previous owner may have left some bills unpaid, which you’ll need to take care of as well.
Just like any other big-ticket purchase, you need to carefully inspect a house before buying it and moving in. If you have next to zero knowledge about this aspect, seek the help of your real estate agent.
