Looking to purchase an income producing ag property, farm and pasture land, that also has a massive gravel production site, over 20 acres of it (approximately 400,000 tons). My approval odds aren't great, I'm a first ...

It looks like you are not able to get lending because your Debt-to-Income ratio is too high.You should figure out what your DTI ratio is.If you are buying cash-flowing rentals, your rentals should actually be helping you get future loans easier.

I have 1 rental via house hack that we lived in for 2 years and slowly increased the value over the 2 years.

Airbnb- house go off the market for housing.  

I've bid on a house on Hubzu and was the highest bidder when the auction ended.

I cleared $10k on my first one.We ended up clearing $30k on the second one.The last flip was very stressful for my wife and she wants to keep our finances (HELOC) out of the next one.I am going to look to find a financing partner to cover the carrying costs of the next flip.On a $400k house (average for my area), the total investment would be $85-$95k and would be paid directly to the lender and subs/suppliers, not to me.I can bring the lender, as I have a good rep with the one I use.I will do all the rest.

Typically, with fix-and-flip loans, you complete the renovations upfront, and then the lender reimburses you via the draw schedule.

The house is going to dampen the value of the park as a singular investment and subsequently the park is going to dampen the value of the house. 

With ADU Geeks he worked all over San Diego so I would be very surprised if he hasn't worked in La Mesa.HELOC is always the most firm route - I have recently learned of some solar companies funding home improvement loans that I am looking into myself.
