I don't know if I should rent out the house and hold it for several years, BRRR the house and sell it in a year or so, try and build a business on the additional lot, or try and find a commercial property investor to sell it all.

Anyone have any suggestions?

I was looking for an individual that may have more experience in my specific market that can offer suggestions or advice with my projected plans. 

I suggest you read up on the BRRRR method (Bigger Pockets has a good book on exactly this).

Your Lender My suggestion to find #2 & #4 would be to go to the top of this page and click on FIND AN AGENT & FIND A LENDER.

More maintenance on the balcony depends on the values. we have 7 zips we build a triplex in and some of them we have considered adding balconies if the market calls for it. another way to do it is on the back where the walk up is if they are truly apartments you can add it there. depends on the level you are after. 

Any suggestions on which credit card I should get for my rental property?

Maybe not 0%, but pretty close.)I’m also saying it could cost them $50 or $100k in additional taxes.

If they're overcharging you however, then I'd suggest getting a new management company, as I don't believe that's an ethical way to do business.  

Additionally, our efficient project management and marketing strategies ensured the property was presented attractively to potential buyers.
