My taxable stock market index fund would be where I pull from in an emergency. 

School and city bond measures pass quietly.

Quote from @Dustin Smalley: The best funding advice for new flippers is to get prepared before you bring a deal to a lender.

With new construction picking up again, I’m seeing investors asking about everything from construction-only loans to full build-and-hold structures.If you’re building this year, what’s your experience been with funding availability and requirements?

I have tried exploring the accessibility I have to those whom may be able to fund the deal yet I haven’t succeeded in finding the proper resources to make it come to fruition.

They want to know you won’t blow the rehab budget, stall out, or panic when something goes sideways.Once I had one project under my belt with clean documentation, lenders stopped questioning my ARVs and started competing for my business.A few lessons from that first deal:• Show up with a real scope of work• Know your comps better than the lender• Bring a contractor who’s licensed, insured, and organized• Present the numbers like a business, not a hopeAfter that, funding becomes a systems game instead of a confidence test.

BiggerPockets Money podcast has mentioned a few times about Pine Financial Group Fund V as a "truly passive real estate" investment.

Sticking to just one funding source is too limiting.I've actually used that exact strategy you mentioned (private money for the gap, bridged by a short-term loan) to make a deal work.

Do i take out the net 200 for funding this realestate investment out of my retirement or my house?

Deal flow, funding, contractors, or timelines?
