I would highly encourage paying a GC to walk deals out the gate, have them give a scope of work so you can see what items costs.

And second question, do you have any PM platform that you would recommend?

You'll lose rent while property is vacant, and you'll probably have to do more repairs to attract a new tenant than you would to keep the current tenant.Is all that worth requiring a tenant to use one specific payment platform?

I'd list them simultaneously & just getting bookings no matter which platform it's from. 

I continue to see new platforms promise ease of use, lightning-fast approvals, and streamlined processes.

Hi, I just started using BiggerPockets and am excited to learn about the community and all the resources available. I'm particularly excited to find others in my area and start to attend some meetup groups!

I know Shopify typically is a more commerce base platform.

You shouldn’t have to go to a second platform to verify a booking.I’m happy to jump on a call to review your current occupancy compared to the market, as well as “the anatomy of a statement.”

The referral fees, which operate similar to a multi-level marketing models, often incent these students to post the rare assignment fee check that does get done to every social platform they can and make it seem like they have an "in' with the guru leading the program. 

I switched to Baselane, which is a banking AND bookkeeping platform and it has been so much easier for me to manage myself.
