I have a mortgage on one house, but the house is too small for my family of 5 (our third child was unexpected). We have council restrictions on extensions. Instead of selling and/or renting is it feasible to keep this house and rent it out and buy another house suitable for our needs? To sell this one our equity would not be too great, but potentially it will raise in value over the next few years. We owe $300k, house value about $380-410k (I think). Potential rental about $280-300 per week. Houses in the area that have 4 bedrooms about $450K. We both earn combined about $90-100k per annum. Any info/advice would be great, as we are going slightly mad tripping over each other (and the kids are growing).
