I used Design Appruv on my first ADU and they have since gone bankrupt and stole everyone's money :/...so don't use them, but do look up their Yelp reviews if you want a good chuckle.My buddy CJ just left ADU Geeks and is starting his own company - I think for quite a significant discount. 

Buy once, cry once.We have a heloc on our primary and my bank just promoted a very discounted rate for 6mo.

From what I've heard some real estate buying agents are moving on to become TC, others are considering the fix & flip business model capitalizing on what they do know and that is locating discounted properties coupled with there knowledge of sales simply need financial backing.

I normally look to buy units at a 20-30% discount compared to the area and develop a business plan to create equity via forced apprecation, primarily on commercial properties (5+ unit multifamily).

The goal is to take down 5-20 million dollar deals; the next few years will be properties that will come to market at very prominent discount. 

I used my own money for these because, with these deep discounts, the seller wants to close quickly.Can anyone suggest how to find someone to be ready to finance similar properties?   

It is not really true because to get the same rate it will cost much more in upfront costs in either origination or discount fees, AND much higher back end fees in pre-payment penalties.

Now, not so much unless you are buying at deep discount and are getting materials and labor much cheaper than normal.

This is common practice of discount airlines.

North Texas is an optimal market for long-term growth, so unless you get a serious discount, I would go for a single-home over a duplex.
