Is there more money in flipping or in new residential construction?

[Lucero Sanchez]

We have 2 houses free and clear one is worth over $100k and the other over $200k, one we have been renting it out for 3 years and get $10k a year in rental income, the other house we live in so no income from that one. We do not qualify for any kind of bank loan so our plan is to cash in on both houses, but we don't know which is best flipping or building new homes (my husband will do most of the building since he has the experience), What would be best? Any advise or suggestions on what we can do?
