I really need help for anyone who is willing to lend me some advice.This is a multi question post!

Currently they need to be purchased with 100% cash, or, 50% down with high interest lending.  

I just invested in a multifamily syndication there.

Where do i find a lending institution in my area that works with Vendee loans?

Most HMLs will want to see that you have similar rehab experience on the 4 renals you own and will lend up to 70-75% of the ARV. 

I live in the US and some of the questions I have involve lending options to help me out with the construction loan and approaches to managing the property as a short-term vacation rental.

There are some serious housing perks with my new job offer: 1) $150K in a 0% interest forgivable loan for downpayment (10% forgiven each year 2) a special home loan program that is currently lending at an interest rate of 4.1%. 3) Can join a waitlist for on-campus faculty housing that is sold for at 50-75% of the fair market value consequently when you sell you are capped at how much you can sell for; waitlist for these homes is approximately 7-10 years and you can stay there until you die).

That is, @Bill B. is correct.While true that it’s harder to find P/HMLs willing to lend in second position than first, it’s also true that many of these will only lend behind a large conventional lender, such as a bank.

And no other buyers can get a loan on this thing either because there's no income to show.Anybody have any lending sources that might do this as a value add project?   

Federal regulators HATE real estate investors, therefore, banks don't like to lend to them (us).
