If you can raise money without stressing out completely, than go for it.

I mainly am curious how people have raised capital for their first properties. 

Acquiring Clients: For those who’ve raised capital successfully and built a strong network of clients, how did you go about finding and nurturing those relationships?

Over time I internalized Dave’s words and made them my own; taking on nearly all the fund investor calls, building and managing the Investor Relations team and overseeing the process of raising over $80MM together.

Now on raising $ side of things, I suggest first you do some research on syndications.

If you're having to go out and "raise" your entry fee, you might want to think about other investments until your cash grows.

I have flipped new homes and townhomes but phased out raising a family and now am focused on utilizing my skills which are building, selling, expanding a circle of influence to focus my effort on the above.

It is not clear to my what you waht from your post.You raised 4M in 2 months. 

I’m asking because I plan to eventually scale and get into multifamily syndication, and I know learning to raise capital will be a crucial skill.Scaling with Private Lenders: Once I’ve done a few flips, I’m thinking of finding a group of private lenders to help me scale the business.

While sophistication of your equity partners (private money lenders) will vary between residential and commercial, the principle of raising private capital is the same.You need to develop your own system which allows a constant stream of PML even when you don't need the funds and/or don't have an active deal under contract.For example; I raise private capital by offering free educational workshops for people with self-directed IRAs.
