It can also get complex managing multiple entities with annual reports and tax filings.

While some less experienced Realtors may shy away from courthouse sales due to the complexities involved, I recognized the tremendous potential this presented and dove in headfirst.How did you find this deal and how did you negotiate it?

so just let it rip and buy that 100 unit complex in Nashville at a 3% cap rate, what could possibly go wrong?

It all depends on how complex your taxes are and who you are using to complete them. lol

Unlikely.80% of our landlords use Excel or bar napkins or some combo. 60% of our small business owners are single-shingle "one man bands," and they too use Excel.QBO, Waveapps, Freshbooks, Stalebooks, SloppyBooks, Xero, One and all the others are nice to have but not must haves until you have several rentals or complex rentals (such as a strip mall or something).

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.

While it may seem like a simple concept, it's actually a very complex process that requires significant documentation as well as specific methodologies.

@Jonathan Snider another con may include the fact that you will now have multi state nexus and tax liabilities, which often times increases complexity for unaware investors

At one point in time we owned a 24-unit and a 272-unit apartment complex. 

Just because something can be done doesn't mean that you should do it.I would not own real estate within a retirement account(including SDIRA).Reasons1) Complexities with RMD2) Lose out on depreciation3) Appreciation when sold would be taxed at marginal rates instead of preferred long-term capital gain rates4) Etc
