Hello,I am hoping to gain some advice in deciding between multiple HELOC options.

If the borrower is very liquid and they are rate-conscious, typically borrower paid comp is a better option.

(I will not be providing a share network for the tenants).I'd appreciate any advice, recommendations, or insights you can offer regarding security system options, installation, and any other relevant tips.

To your point about being concerned that a seller is upset if he/she sees a large assignment fee on the HUD, an option to consider is a SDDC (Same Day Double Close).

They do have an option to do the research for you if you email them.

Those are two different conversations.First, you can save even more now, but if you want to move out, house hacking would be your best option, not paying in cash.

Some lenders will work with any level of investor experience, credit scores as low as 660 and can close in as little as 10 days (there are loan options for 640-660 credit scores- they require 20% down).Another good thing is interest only and 6-24 month loan terms- you can refinance by selling or refinancing to a long term DSCR rental property loan at any time once you complete the rehab.

If you cannot find a source for this money another option is to bootstrap it.

One of our markets has a cap on the number of STR licenses with a huge waiting list and very few licenses changing hands over the last few years, so that doesn’t appear to be an option for us in the short run. 

I would not think flipping first either, it's a rabbit hole and with no money, your options would be hard money which is a hard ask right now for first timers.
