I have been having this same thought lately but haven't had any luck finding out more information. 

I updated the bathroom/porch in the spring, and am finishing construction on a 2-stall garage (the previous garage was basically a large shed that I could not fit much in).Moving forward I am considering one of the following options to put my money and build equity:1.

Depending on the ARV, I think you are better of using your own cash or getting a partner involved to finish the rehab and then cash out refinance with a conventional or DSCR loan.

There are companies out there that have 0 skin in the game and are just referral sources and there are others who are vertically integrated so they own/manage the entire process from start to finish. 

Who is paying rent, who's always late, who's calling for what repairs. 

We are finishing up some renovations on a house with an in-law on Cape Cod.

Oh that’s worth half what it was two weeks late?

Perform the same task in each app to ensure a fair comparison.Load a property with pictures and details.Market that property.See what your marketing looks like from the public's perspective.Submit a fake application to see how easy the process is.Run a credit/screening report on yourself.Enter a maintenance request, assign a vendor, and attach a fake invoice.Enter charges to the tenant's ledger.Enter recurring charges and automatic late fees.Sign documents electronically.Run owner reports.After testing a few apps, one should clearly stand out.

Then your agent can still work for you on seeing this to the finish line. 

STR income will always be dependent on who I managing the property, how nice the finishes and furnishings are, and the actual location of a property within the given city.With my STR in Destin, numbers are more or less the same as last year, perhaps down just a hair.
