It's time for another couple of questions in this week's edition of 'Ask Rob & Rob'. Two listeners... ...ask Rob & Rob...What's the best way to keep builders on track? PLUS: How do interest-only mortgages work? ASK YOUR OWN QUESTION TO ROB & ROB! Don't be shy! All you need to do is leave a message with your name and whatever's on your mind. Just pick up the phone and call 013 808 00035 (normal UK call rates apply). Or if you prefer, click here to leave a recording via your computer instead. NEED MORE ANSWERS? The Property Hub Summit is the place to get all your questions personally answered by Rob & Rob, and build a network of other smart, motivated investors. Over the course of a full day at a swanky hotel we'll help you set your goals, form a plan to get you there, overcome your obstacles, and give you the support system you need to make sure nothing gets in your way. Just don't hang around - there are only four Summits each year, and just 16 places available at each! Interested? Click here to find out more.
