Also used the HP 12C long ago, but prefer the BAII.I have not used Excel but understand it's very good, my last cell row program was in the early 80's, my BAII was much faster and using my head.I have never used any BP calculators, haven't even checked them.

As others point out, they may have more money, cheaper money, better vendors/contractors to do better, faster work cheaper but, if you are a mom and pop player with the intent of buying at the courthouse steps and you have the money to do it, go for it.

I find that it's faster and easier to learn local real estate tactics from experts working the same area as me.  

I guess for me, I'm reaching my ropes on the corporate world faster than I ever intended.

Last house I paid $35 for quartz to brighten up a dark kitchen, it’s almost as cheap now  It pays for itself with faster rentals, and then pays again with less maintenance and damage, and then finally pays for itself again if you ever sell. 

You'll grow your cash flow and equity much faster.

You may not get a huge ROI, but I can almost guarantee it will help the home sell faster.

Also, they hopefully already have relationships with plumbers, electricians etc. and can get them in there faster.

Erentpayment is faster but costs $3.

You could simply wait it out, and slowly build the capital to do something else, but I'm guessing that you want to go faster (two deals in two years is fast for a new investor who is self-funding).I'd be happy to talk to you about this with more specifics, if you have the time or the inclination.
