No personal income or tax returns are required.

Quote from @Michael Overall: Good day, If an investor has 10 rentals and wanted to over time sell them and put the money tax free from a 1031 toward a large purchase is there a process to do that? 

Follow your state regulations on notices but do everything you can to avoid an eviction.

If you are taking out a conventional mortgage of any kind, you can't buy in the LLC as it does not have two years of tax returns.You are also asking if an entire state is good to buy multifamily, which means you are too soon in the process to even talk about buying.

With down payments as low as 5-10%, plus low property taxes compared to the U.S., investing in German real estate is more accessible than you might think.If you’ve ever thought about owning property overseas but felt intimidated, stay tuned.

High taxes.

I think people were/are just trying to avoid agreeable gray.

After closing, when the property taxes were due I never received any bill.

Generally speaking, with SFR or small multis, I just rely on the lease/rent roll (and some form of proof of payment; i.e. bank statements, deposit receipts, tax returns, etc.). 

I also wanted to benefit from tax saving before the years end with a new property purchase.
