A realtor who used to have a PM company called "JBS Realty" until this month.He used to manage 8 of my properties and is currently refusing to pay out multiple 5-figures worth of rents/property reserves/security deposits/unpaid utility bills owed. 

Even if they do pay all the taxes, they don't get to use the benefits they are paying for (medicare, social security, etc.).

I was able to secure $27k from them and $8k from our savings and the deal went through!

Certainly one account for each LLC, (separate for security deposits based on your local rules)

You might also delay refinancing until the property value or rent increases, which could secure better terms or higher returns.

Would it be a good idea to take a deposit to secure the deal until the rule clears?

This would put downward pressure on mortgage rates, making financing more attractive.Investor takeaway: Secure financing now in preparation for lower rates.

I completely agree with the importance of securing a good W2 job, living below my means, and investing in real estate early on.

Now, I'm imaging a scenario when every one of these tenants move out that I'll be paying their entire security deposit + interest even if there are damages beyond normal wear and tear. 

Did your borrowers mention securing your investment with a recorded mortgage or deed of trust, personal guarantees, lender’s title insurance, or anything else?
