Feedback taken and internalized.

If they aren't able to reduce your taxes then they don't get paid.I assume they are selective about which appeals they will take on since there is no benefit to them or the homeowner to not be able to win an appeal, but I have no knowledge of their internal business logic. 

I do have a handful of clients that have ended up using multiple CPAs just due to who their partners were on different deals, and even in those cases they almost always end up consolidating to a single CPA - taxes are enough of a headache without dealing with 3 different professionals who each only have a slice of the whole picture.If you are going to regularly be investing across the country, it doesn't hurt to work with a firm that has State and Local Tax (often referred to as "SALT") internal resources, though typically this does come from larger firms with larger fees. 

Building a credit history...all on point.Things that I would also start looking at: where do you want to invest - locally, nationally, internationally?

In case anyone else is wondering about this, it's my understanding after doing a ton of research (but not having talked to a professional) that bonus depreciation only applies to properties in the US (not international properties).

We use Quickbooks to manage some of our internal tasks like expense tracking, invoicing, etc. but Use bench to manage all of the more tedious tasks like bank recs. and tax prep.

I would advise you to approve this applicant unless there is a strong, objective reason not to - such as eviction history, a recent criminal conviction, or their income (including all disability income) is less than whatever standard you have used for all of your past tenants.  

I speak to the estate planning attorney on Wed (I have another property in Philadelphia in my name that needs to be sorted as I'm currently exposed liability wise and another internationally also in my name that I am about to start STR) so I want to read up before that meeting.Thanks!

A lot of them will have criminal backgrounds.

I did self manage and self lease, so I screened all tenants looking for no evictions, no criminal background, good landlord references, long term tenancy, etc.
