Need Advice on refinance and long term plan (First Time Investor)

[Chinku Chinku]

Got a townhome in suburb area of Houston for long term rental close to katy mills (<5miles). It took quite a good time (~6months) even with a property manager but finally found the renter after rent decrease by 200$. Learnt lesson not to fully depend on property manager and should have made decision faster by reducing rent . Currently started renting it for 2300$ per month , need your suggestion things I can do to fix my below situation. 
Trying to save $$ so I can prepare emergency funds in case of any major repairs etc . Understood I made a bad move here as this was first investment so didnt think much except at the location for longterm growth or possibly I move there as part relocation. If I have some cash do you recommend clearing the loan or invest instead for next property with proper planning ?  Thanks in advance

Down payment: ~90k (25% downpayment)

Rent per month: 2300 (5Bed, 4 Bath) with 2100sqft

Property management: ~150 (monthly)

Outstanding loan around : ~268k (7.675% APR) 30years fixed

Landlord Insurance: 1500$ (per year)

HOA: 1600$ (per year)

Keeping an eye on interest rates for refinance, so I can then move this property to an LLC instead. Need your guidance here if I should wait or just move it regardless sooner.
