I wasn’t prepared to invest this amount of money in the first few years, so I'm unsure how to proceed.Due to the high interest rates at the moment, mine being at 7%, and with two tenants paying below-market rents, I currently have no cash flow.

I don't think they want to subsidize units going above market rate without a good reason.

With interest rate so high - 7.2% in my case.

A commercial loan is probably going to be higher rate and yes will tie you up personally and the business.

Does anyone have any recommend where I can get lowest insurance rate.

Sell - Would prefer to avoid this to keep my low interest rate (3.3%) and avoid fees/taxes. 

I have acquired the property through a short term loan with a ballon period of one year and at higher interest rate (12.99 percent).

When you receive seller concessions you can have the interest rate bought down 3% for conventional & 6% for FHA buyers.

With a locked-in low mortgage rate of 3.2%, and about $100k in equity after expenses, I'm contemplating my next move.
