The limited partner privately sold his share to another investor in the syndication but at a 35% discount.

I self represented myself in the deal and had a private money lender to finance 100% of purchase and 100% o rehab.

I also sent you a private message.

As other's noted, the primary ways to gain more money are:Bring in partners for the equityTake on more debt, either through HELOCs, refi's, hard money or private lendersMake more money yourself.The most common way people scale is through the first two.  

What would add value would be fencing the yards apart from one another so each unit has a private, fully-fenced yard.Put the mowing into your tenant's lease.

 I have got in contact with lenders that offer 80-90% LTC, what are other ways of financing the out-of-pocket LTC without using my own money?

@Jeremy Altdorfer The only possibility is some sort of "Private lender"  (friends, famly or associates.

Feel free to private message me for contact information.  

Located in Harnett County, the community has a private river access and boat ramp.

The overwhelming opinion on the forums is to open up private offerings to everyone and I get criticized when I suggest otherwise.
