I do manage some small apartment complexes and generally there are not too many issues, but not zero.Also, for me as a PM I have fixed costs per unit, so to have 5 listings in 1 house would be cost prohibitive.Just food for thought, good luck!

We built BNB Calc because our team is STR investors ourselves, and the tools out there lacked these other features needed for thorough due diligence. 

It appears that you have a complex structure already suggested to you(PM company, S-Corp, Investment LLC, etc).Who suggested this structure to you and what did they say was the benefit for setting all these companies up?

Additionally, using a land trust with an LLC could offer protection without the complexity of multiple LLCs.

If you have tax planning and complex items within the return, I could see it getting there but it seems a little bit high.

If you have the resources to buy a 150 unit apartment complex then again getting that done is a year is achievable.

For your "BRRRR in Bulk" approach, you might want to explore lenders that specialize in portfolio or DSCR (Debt Service Coverage Ratio) loans, as they are often more flexible with complex financing structures like seller 2nd notes.

Maybe some affordable housing complexes. 

This is a general question for security deposit deductions made by a landlord of a complex.

I can justify any price (and some high fee syndicators are still doing so), if I just play with assumptions, prepay and buy down my interest rate, and hope that sub-5% cap rates will be returning in the next few years.But if you know your market and market cycle, have an idea where interest rates may be going (this is an educated guess for all of us), and then have your assumptions, you can certainly have the conversations you reference with brokers and see what their take is on pricing and if it is worth writing.Finally, I have said this before and will continue to say it, whether we are talking single family homes or 400 unit apartment complexes, off-market purchases do not make something a deal.
