My husband and I are looking for wholesale deals, rehabs and buy-and-hold multi-families.

You have to know what you are trying to accomplish (flip, hold, where you want to be equity wise, if holding how much rent you'd get, etc) is very likely to happen as planned given all the data.

I am currently educating myself on the best tactics for wholesaling property, as well as strategies for buying, holding, and renting properties to generate cash flow.

I really want to do flips as well as buy and holds (ideally multi-family units, apartments are the goal).

If you want to hold for a while take a look at the cities light rail and the future plans.  

Additional info:primary 1031 exchange rules and requirements include: 1) same taxpayer: the taxpayer who sells is the taxpayer who buys, 2) property identification within 45 calendar days post closing of the first property, 3) purchase of the replacement property within 180 calendar days, 4) trading up: the price of the replacement property is equal to or greater than the old or relinquished property, 5) hold time supports the intent to hold for investment, and 6) related party transaction regulations. 

I am looking into buying my first buy and hold property.

Our goal is to acquire a mixture of properties single-family and multifamily to buy  and hold

In the next few years, I hope to be able to start investing in real estate (buy and hold, multis), and in the next couple of year I will probably be purchasing a new personal residence.

First of all,  Security deposits  as rent should ONLY occur on the last month, and never before then - - otherwise you have nothing to hold over for damages on move out.QB is poor when managing security deposits, and when I asked this on a QB forum, you should have seen the procedural mess that was suggested to make it all work.
