I am looking to get some help about new construction of low cost new housing in Houston and sourcing areas.

You can be the cash source, while they're the hustle.Just make sure you vet them super carefully and do NOT go with someone who hasn't done a handful of deals.Goodluck!

Establishing a strong and varied source of investor friendly lenders is key to growing a large portfolio.

As long as you buy right and don’t over leverage, I think HELOCs are a really good source for $$.

The key is often arranging a system that when that client is ready to buy again or sell, you point them to work with the referral source first (in the event you offer in-house brokerage services). 

By the time you are ready to move again you would at least have a good place to fall back to or a steady source of income.

I work with an exclusive group of investors to source off market inventory in Philadelphia and the surrounding suburbs and get some pretty good inventory at a high volume in the neighborhoods I mentioned above.

I’m just so used to BP being the “source” that I hadn’t even considered looking on around the internet (meetup.com, Facebook, etc)

As far as just handing out sources there is no business where someone would just hand it out to a new contact.

oooh.. secondary point... there are other sources, publicly available sources, for a useable portion of this data depending on the county.
