Personally I only use my HELOC on short term projects like flips, new builds and BRRRRs where I know I will be replacing the capital within months.You may be better off waiting a year and save up more cash or liquidate your index funds if the returns on a property will be better.

Find yourself a good team who builds ADU's has a project management team and of course has all the licenses and insurances to protect your property.Quote from @Michael Adamo: Hi BP Community,I’m exploring adding one or two ADUs to a property I own in the Miracle Mile area, near 3rd Street and La Brea in Los Angeles.

Its a tough subject because logically, they are joint and several guarantys so rationally a 100% guaranty from each of two people (one 740 one 680 for example) is ALWAYS going to be better than just one 100% guaranty from someone at 740 (so it wouldn't make sense to have a better rate for the latter)The problem is that there is fraud and "straw borrowers" out there where someone who is not involved in the property signs on to boost score and terms - so many DSCR Lenders in response either do the "non-rational" thing and price to the lower to avoid the fraud or use the higher of the two (and either be a little loose with things or just stay vigilant on any funny business)

Ensure the STR’s projected income comfortably covers new debt, even with conservative occupancy rates, and maintain reserves for market changes or vacancies.

As far as what you are asking, it will be very tough, and probably impossible.

I just closed on yesterday that is in Clearwater and closed for $660k with all furnishing and it projected to do over $90. 

Most lenders are going to want to see a few big things from the ownership group. 1) The borrower will be the enitity (LLC, S-Corp, etc) and any owner with usually 20% or more of ownership in the entity will be expected to guaranty the loan, 2) We'll want to see some experience doing similar projects from at least one of the main owners, 3) We'll want to see bank statements showing liquidity enough to cover the intial cash injection (down payment), the closing cost, and some cash in reserve.

I'm doing this because then I can cashflow the renovation without having to take out reno loans, it takes a bit longer because projects get done as I have the money to do them but for me I prefer to be a bit more risk adverse and have less debt. 

What I'm most concerned about is the Project 2025 plan to gut HUD and most social services.

They said that kind of project would basically convert the property to an apartment building and requires R6B zoning.
