I do not have experience in commercial real estate transactions.

I feel like in today’s day in age there are so many tools for STR operations and I cannot believe there is no integration for a merchant of sale transaction or some kind of financial app/ software that can take the remitted taxes and pay them to the government automatically.

The lower unit is a basement/guest suite.

On houses below $200k, the 70% rule gives you too low of a profit - you need to lower it the lower you go (ie a $100k ARV would probably be a 60% rule).

Interesting that this seems to cover all property zoned residential, with no apparent carve out for a transaction of residential property between two investors.  

We really want take advantage of accelerated depreciation to lower our tax liability. 

I would imagine the hold back is lower.  

I opened an account, a Solo 401K IRA and completed the transaction.

Since you mentioned REI Hub, I worked with REI Hub in the past and they had the same connection issues but their CEO is usually good about making quick updates to create a better user experience.That being said, there is no perfect solution out there regarding bank feed connections so I'd go with one you know and ensure the accounts are linked on a weekly basis to be confident every transaction is flowing through without interruptions.

.- Investors get access to real estate cash flow with lower costs and no landlord responsibilities.- The whole process is simplified—no co-ownership legal headaches.I’m curious about the pros and cons of something like this.
