I am seeking recommendations for a Registered Agent to handle LLC setup and related filings for new real estate investment business that my partner and I would like to set up. 

I have personally seen subs who specialize in storm water management systems as well if that's something that is necessary.

Our efficient project management ensured the renovations were completed on time and within budget.

My concerns are debts that weren’t paid or charged off if it was recent and especially if it was property related (utilities, rent, etc).  7 times the rent just means that make a ton of money and spend a ton of money.  

Currently, I manage three villas for rent.

There is a relatively long history on the rental income from the previous owners.

My wife and I work together to purchase and manage our rental portfolio.

We have an S-Corp that manages both LLCs, so I can take payroll and contribute to retirement accounts. 

But if you took a HELOC, which tends to have relatively high interest rates, your blended rate (the average of what you're paying on your mortgage plus the rate on the HELOC) would likely be in the same range as today's mortgage rate.You'd also only be renting out one unit, but by selling it might allow you to get more than one additional unit and still grow your portfolio. 

My wife is a property manager here in CT.
