If you do them, then make sure you are hiring a vetted professional.

So my advice: understand your market and local regulations, avoid the average cookie cutter STR home, make your home STAND OUT and be aware of the significant upfront cost needed to do so, and absolutely hire a local PM company.

I prefer to hire concrete cutting because they will use a big hydraulic powered saw with the power unit on their truck.

Avoid anything with condo association fees or homeowner association fees as they DECREASE CASH FLOW with no real contribution to the bottom line.Lastly, since you are new, when you do get a property DO NOT HIRE A PROPERTY MANAGER.  

Contact a Section 8 representative, preferably whoever your tenant's rep is if they have one.

I agree with Michael.You can still self manage but you need to hire out more tasks.

Once you qualify for REPS, your current losses are unlocked but your past suspended losses remain locked. 

As you scale, if bookkeeping isn't fun for you, consider hiring a bookkeeper for a couple hundred bucks per month.We do 20 out of state Flips/BRRRRs per year and use QuickBooks Online to manage all of our finances for rehabs. 

I've done the spreadsheets for a decade and then hired someone to outsource books entirely, I think at 50 to 100 units it makes sense to buy software.

Right now she'd struggle to meet the 750 hour requirement for REPS.
