My sister is having a rough time, should I rent to her until she can get back on her feet?

Though your intentions may be good, your obligations to family can blur your needs as an investor in rental properties.

First consider what got your sister in this position to begin with. Will she be able to afford the rent?

If not, will you be able to carry the weight of an extra mortgage, insurance and taxes? Who will cover the utilities?

Not to mention, if she can't pay, will you be able to evict your sister? Avoid a family feud and rent to someone better qualified (and not in your family tree!)
