Most cost effective way to go is SERIES LLC.

Multi-family investment and home hacking are both effective tactics.

@Noyessie HubertIf you plan to rehab all the units, if is more efficient and cost effective to do them at the same time.

Are there alternative ways to do this that are more hands free for me but still effective? 

Should I have the agent send three separate offers, or is it more effective to choose one offer and include a letter that outlines the other options?

I have also had a lot of seller's this year and every single one of them was willing to offer 2.5% to the buyer's agent and did not want to wait till the change goes into effect to list.  

For example, both of the following are possible: 1) Extreme leverage - an "All-in" bet on appreciation: A syndicator can raise capital for multifamily, take out bridge debt on a low-cap rate property, and then lever up again with preferred equity to effectively give the common equity a 90%+ leverage.

The Landlord insurance policy quotes I am receiving has a high deductible for Wind/Hail/Named Storm coverage which effectively means replacing the roof would be out of pocket for me which defeats the purpose of carrying this insurance.

They effectively said they would leave a bad review if we didn't fully refund their stay. 

I think if you set up a brokerage account with the same bank that your business checking account for the LLC is at, you can simply move the money from the checking account into the brokerage account and then purchase something. like USFR, which pays 5.4% in T bills with zero risk of loss or BKN which pays 5.7% in tax free Municipal bonds if able to tolerate some risk (this gives me a >9% tax effective rate on my cash).
