Or the easiest is but an add here on BP.

If you are syndicating or partnering with other investors to fund a Sponsor's deal and you are a company doing this (LLC, partnership) then get a PPM attorney and file with the SEC. 506B is easiest but if it is really risky...then 506C is best. 

I also would like to get into the BRRRR method.

My primary focus is on the BRRR method, with a greater emphasis on appreciation over cash flow.For those with experience investing in Cleveland, I’d greatly appreciate any insights on neighborhoods worth focusing on.

For all methods you would want to find a market that has strong employment rates, strong income rates for the market, and is a growing or an established market. 

Normally it's single family or multi-family that's the easiest place to begin.

As a general contractor, i feel best suited for fix and flip or BRRR method investing.

I do not have to much cash for a down payment but was thinking of doing a HELOC on one of the rentals to get more cash and go the BRRRR method.

What is your preferred method of contact and when is a good time? 

Yes, the BRRRR method can work with multifamily properties, and many investors have done it successfully.
