Houston is an excellent market for multifamily investments.

This is effectively legislation to open up the market to new prospects. 

I'm looking to connect and network with other investors, contractors etc who have experience in this market. 

It is not typical that you will find SF deal after deal, and if you are actively marketing for distressed sellers many...most...will want cash sales.

Purchase price: $230,000 Cash invested: $283,550 Sale price: $283,500 Purchased off market. $25,000 Rehab. $20,000 profit after realtor commission.

Furthermore, @Dave Meyer has a YouTube show/podcast on market trends for your reference.

Submitting a form D to the SEC is negligible and then each state someone is in that invests you must file a form d in that state as well which can bea  few bucks to a few hundred bucks.Where you will incur the greatest cost is raising the actual capital and marketing etc. 

I was wondering if anyone knew how I can connect with or market to investors who specifically purchase land/ lots? 

You'll likely want someone that can handle A to Z with marketing, pricing, cleaning, maintanence, decor, websites, reviews etc.

I was thinking of starting a rent increase for my 1 bedroom tenant voucher due it being low and well under fair market value(Based on  hud and zip code) but my tenant is in the process of having a caretaker for her disability and getting approved for a two bedroom voucher.
