He has verbally stated that he's open to holding the mortgages privately but hasn't sent us the property locations yet, just general areas.

Our total mortgage amount is 165k and our total out of pocket is about 9k, that's closing costs, fees, insurance, appraisals everything.

It also, by the way, represents a risk with commerical mortgages that are often 5-7 year fixed rate terms with a balloon payment.

We're currently doubling our mortgage payment, should we stop?

The GI Bill is not of any use in terms of using income to qualify for mortgages, from what I understand.  

I can't tell from your post, but if you are just speaking of multifamily meaning a duplex or triplex to house hack to pay your mortgage, then I would focus on where you can get a good professional job first, then look in that market for a place where the numbers work to house hack.If you are looking at larger multifamily in Memphis, then try to talk to @Erik Nowacki who moved from CA to Memphis to own and manage multifamily.

So my grandmother is 80 years old and just stopped working officially last week.She owns a home and stills pays a mortgage on the property and since shes no longer working,does not have the means to pay her mortgage any more.I currently live with her and told her i wouldnt mind paying the full mortgage costs and all the bills that entail in owning a home but i would like to be a co-owner and when she passes the sole owner of the property.The house has been appraised at around 400 thousand and she owes currently about 225 thousand.I wanna know what options i have that maybe i havent heard of or seen,any insight or ideas are greatly appreciated.Thanks in advance,Alex.

Make a spreadsheet and take your total rent and subtract vacancy, mortgage, capital expenditures/Maintenance, Tax, insurance, and property management (You always want to include this just incase down the road you end up using property management).

If it is a loan, and you claim it as a gift on the mortgage application, it is fraud and very slippery slope.Tread carefully. 

For example, there was a triplex that is out of my current monthly payment range; however, with the potential rental income, the mortgage payments will only be a few dollars over.
