Are there any 30 year DSCR or Portfolio loans that would fund such a deal?

It was not a big deal for him as he already owned it as an LTR previously and furnished it in hopes of using it as a second home when he lived in CA.  

I look for BRRRR properties and am always interested in a deal

Those I know who've been successful in the Houston market usually are doing off-market deals. 

Would you consider this a good deal.

There is not much buyers out there buying, on the flip side I have been able to buy 4 properties this month that were really good deals.

Otherwise, you'll likely never get the deal done. 

There are so many moving parts in a BRRRR deal that you need the security of your primary income.

If I were to partner with a developer to build houses to sell, how would you structure a deal?

I'm thinking the liquidity of the HELOC would be great to pull the trigger on a good deal when it comes and I don't want to pay interest on taking out money I'm not actually using yet since I haven't found a property yet.
