I would like to pull out as much as I can to start and buy a multi unit.

There is no pull down ladder and I have reason to believe there may be some “cost cutting” going on up there seeing as how it’s a flip and I noticed cost cutting in other areas of the home.

Im close to pulling the trigger on a Rental property.

I have been pre-approved through the traditional means (20-25% down) but I have been recently offered, by someone I trust, to borrow money from them using money they will pull out of a HELOC on their primary residence.

Real estate agents and appraisers have access to their local MLS (Multiple Listing Service) and can pull all the recent sales data for a particular area. 

You can also refinance the property and pull out a good portion of your equity that way.

You can call multiple lenders and have the conversation where you go over current rates, terms, etc and they won't have to do a credit pull until your ready to pull the trigger.

Sounds like you have a good opportunity so go for it, or is this your first deal and you're concerned about pulling the trigger. 

So far no issues as banks usually only pull title work for a property of an existing loan if they are concerned about the loan getting paid (loan being severely past due) or if they have any suspicions.

It's kind of like a BRRRR without renters, since we might pull money out.We have a friend couple who have done this with three homes now.
