Build-to-rent communities, purpose-built neighborhoods consisting entirely of rental units, are stepping in to fill this void, providing a viable alternative to traditional homeownership.Unlike traditional single-family homes or apartment complexes, BTR communities offer a range of housing options, from detached houses to townhomes and duplexes, tailored specifically for renters.

Its a great lower priced option to get into the game 

If a commercial property such as 9+ residential units (such as an apartment building) or not residential, the below doesn't apply. 9+ units typically take extra expenses into consideration such as management fees, utilities, etc. 

Accounting is not my strength so QB's user friendly portal AND bookkeeping services (extra charge) have been just what I've needed.I don't see the benefit in having separate accounts but perhaps someone else from the BP community can weigh in!

With this option , I always have cash available.  

1031 exchange is a great option for upgrading - units, cashflow, class, location.

If you go the partner route just ensure there are clear expectations and you all agree on the exit plan options.

One option - (looks like you've already taken this route) - Shack up with a local investor-minded realtor, they will be more than happy to set you up on a specific, filtered investment property drip campaign. 

With the numbers, all options are good options, just looking for feedback on why you might choose one over the other. 

However, I figured if there was a good credit card with good cash back options, I may as well use that and then pay the bill in full each month while rehabbing.
