Let's say it sells for $300k for numbers sake.Since I have a loan that loan has to be paid off.

Good point, yes a house hack would be more of an owner-occupied loan with a lower downpayment instead of a DCSR loan.

I just had $100M in non performing private lending loans come across my desk.  

I'm just short of 30k and recently I have been getting a lot of loan offers should I accept one of these loans to use for a down payment or is this a bad idea?

Since the loans are not for my primary residence I understand that FHA and VA will not work.

I’ve done the same thing.I’m active duty with three VA loans. 

Do any of you know if a lender would loan to me, if I did rent my home out?

While I'm familiar with LTRs, I have no experience with STRs and acquiring a loan for one.

Assuming you did not invest originally.To clarify, I am coming across some opportunities where a sponsor is in the middle of the biz plan, their loan is reaching maturity, they need extra capital, and they are attempting to raise the extra capital from other LPs rather than or in addition to a capital call.They are offering "rescue capital" investors pref equity that is ahead of original common equity investors.

I am looking into purchasing my first property using an FHA Loan and doing a house hack.
