My biggest advice is to start investing where you have a good network of people you know like and trust...this especially holds true if you will be investing out of state.While it's not impossible to go straight to the commerical I personally found it easier to start in the residential world and then make my way over to commerical multi-family. 

We stopped wholesaling and ended up just networking better with wholesalers and putting more offers out to find better deals.The BRRRR process also has its challenges due to being out of state.

I see this is posted in the house-hack forum so I'll make the assumption that you want to owner-occupy your next investment.To work more hands-on, you'll want to spend time searching for deals, analyzing deals, and networking/building a team.Before your property search, I'd recommend speaking with a lender to find out how much you'll qualify for.

(Keep in mind controlled group rules, meaning if you own a business with W-2 employees, you often can't just setup a side business and open a Solo without giving benefit to your W-2 employees with your main business - another area not often discussed in this industry until it is too late). 5) Lot's of pros with Solo 401(k)'s as you can tell from above with the UDFI exemption on debt financed real estate and ability to make larger contributions.

I will say Long-term rentals are tough to pencil in at the moment, but it can usually be done with a larger down payment.

Its ALL about your network.  

I went out to Memphis in late July to set up a network of agents and contractors.

(i.e. most done work via phone and internet/building networks locally) I am currently in Virginia but want to look at cheaper markets for investments such as Pittsburg, PA.Hope to meet some great like-minded people here!

A larger group of people leave things so neet, you can hardly tell they were there.

This method allows you to take some of the profit tax free and indefinitely defer the rest of tax, using it to purchase larger, nicer property/properties in areas with better cash flow potential.
