Additionally, you should be using OPM to fund most, if not all of your investments. 

this allows me to have an opportunity fund for the quick hits and not have to deal with landlord drama that I cant stand personally there are many other ways in real estate to make a buck and landlording is easiest to understand and get into.. but can be pretty annoying if you get some cruddy tenants or buy in areas were your renting to the bottom of the income pool or those on government assistance.. 

Just from renting rooms in your basement, why is it so hard to find someone to fund the project, with those income numbers....

Is it out of your job, vacation fund, retirement money added to a 401k, taking care of aging parents....You determine what the goal is and the answer will become crystal clear. 

Brought 1st Rental property for $25,000 — Obtained financing based on a subject-to appraisal that came in at $50,000 @ 80% LTV = $40,000.My original thoughts were I would be able to only put $15K into the property and technIcally have none of my own money in the deal.

@William CastiglioneIf you pool both LLC's funds, no debt can be brought to the table.

Since I do need to make repairs to my primary and have about 30k in equity, I'm not sure where to look to for funding the necessary repairs. 

The benefit of this over FHA is that PMI automatically falls off a 78% (or you can request it at 80%) LTV.

Now I absolutely know that I don't HAVE to go and get a business license to start wholesaling properties, but if I have the funds, team, ect. to start a company, should I?

The IRS is just as concerned of the participant paying a higher rate which can be seen as a way to exceed the solo 401k annual contribution rules or to get more funds into the plan.
