Don't get me wrong, there are some great VAs out there, but you have to find them, train them, monitor them and pay them well for them to produce anything above mediocre results. 

Also  beware that  paying a large loan fee  may affect the lenders  ability to do the loan.

I am not familiar with who you are working with but always recommend vetting any company deeply before signing and paying -- those companies tend to have a lot of overhead they need to pay - out of your bottom line.

Buyers who pay a premium for living in one of the nicest areas of the city.

If they want to keep paying at 11 percent, good luck to them.

Plus, you continue to build appreciation through mortgage pay down, as well as market appreciation as well.Timing is up to you… now if your potential new investment will cover the higher interest rates you see today.  

An apartment complex or even a small multifamily where 90% of the residents are paying market rent and 10% is legally set aside below market.

A vacant month, turnover costs, paying your PM to fill the unit.
