Christian - You will be fine renting out the property. 

I no longer qualified for traditional financing because I already own many rental properties and my DTI was high for the bank, so I purchased these in a business entity with a trusted private investor and was able to refi the 1st property/sell the 2nd property to pay back my investor and ultimately keep the better property for zero money down.

- What are the downsides for the landlord, compared to a traditional residential lease to a family for instance?

Quote from @Christian Mattila: I think I can get you in front of the right guy ! 

@Christian Perez We don't use title companies in Georgia. 

I’d like to connect with investors to show the potential of putting homes on land to flip instead of the traditional house flipping strategy.

Since you are essentially buying the property 100% financing between your HELOC and financing, make sure you can afford it as if the property goes south, or you have to short sale it, make sure you are in a financial position to be able to still afford those payments on the LOC. 99% sure you will not find a cash flowing property using traditional financing and the HELOC.

My Experience with Upside Investments:As someone who prioritizes my time but recognizes the potential for wealth creation in real estate, the idea of traditional, hands-on investment wasn't ideal.

Christian You would use a DSCR/Foreign National loan program to get the approval.  

Instead, they typically employ a sales comparison approach to determine the property's worth, using the income to calculate the DSCR, which usually needs to exceed 1.0 for most lenders.Assuming you have a solid track record with the property and there's enough equity in the deal, leveraging the After Repair Value (ARV) on a sales comparison evaluation could enable you to refinance into a bridge loan until the necessary work is completed.Maybe a mortgage broker specializing in traditional loans could offer insights into construction-to-permanent loans
