I have capital that I been saving for awhile now. I am planning to house hack my first multi-family (duplex or triplex). I am using the BP calculator and analyzing deals and when I feel the right one comes around I want to present it to a partner that I know of. I do have capital so that is not the issue the partner is for more like getting approved for so they would be more like an co-signer or something like that.

My question is, what is an actual way I can pay back my partner their money when I have the equity. I am having a hard time getting a loan because I do not collect a "pay stub" every week (I own my own business). So I want to have a co-signer to help me with my purchase, but yet I have all the capital needed. If it turns out that the partner needs to put in some money I want to have a plan also in line that I will pay them back or have an incentive for them.

I had a few ideas as of now such like 

A)let them have 20% of the property so if I decide to sell down the road they will get 20% of the property.

B) Have a pay back plan through a promissory note of the amount they lent to me in a certain amount of time.

C) Have a date set for an example year 3 and pull equity out of the property to pay them back. (but how would I go about doing that?)

I hope that I am thinking in the right direction to come up with a plan. If anyone has had any situation like this I would be curious of how you dealt with a partner and paid them back. Once I get my feet in the door of real estate and have my first property I then assume I will be ok do be able to do it all on my own for more properties. Just this first one I am having a hard time getting approved for.

Thankyou for the advice!
