HostGPO charges you a fixed monthly membership fee.

While technically business purpose loans, these will still basically be 30yr (or whatever tenor) fixed rate mortgages.

there was a follow up post where someone got a loan from them but for realistic rates  8% or so and few points.. under 6% private / hard money simply does not exist unless its a family friends type situation. that bank rates or lower right now for new construction or fix flip  

The training is pretty thorough focused on lending hard/private money to other fix and flip investors, or for my own deals for which I could pay myself as the loan broker.

My wife and I have overhauled our personal budget to reflect the 'pay yourself first' approach (allocate in order: income comes in -> invest -> donate -> fixed expenses -> variable expenses -> fun $$).We are looking to see what experienced people generally recommend for a holding tank for that 'invest' allocation while we target our first real estate deal.What financial vehicles have you guys used that works well for this?

Insurance companies want to fix it the cheapest way possible, and their goal is to minimize out-of-pocket expenses like this one.  

for fix and rental projects or for fix and flips?

If you need current income, I'd recommend another fix/flip.

We have a 30Y Fixed DSCR product that would likely fit your needs.
