I would recommend using a website that is already set up.

Then get your tenants agree to pay that much without using a realtor.

I bought a property using a 203k rehab loan and I was wondering about what will happen if you have reno money left over in your escrow account when you refinance your property?

This might mean refinancing or using a HELOC (Home Equity Line of Credit) to access capital for your next investment.

This includes using a google voice # for tenant calls and texts, having a real estate agent show and rent the place for you, and having a PO Box where bills, legal paperwork, and payments are sent.

Is anyone using a good inventory management system to track supplies in your STR?  

Rent your current house for 2 years and then look at selling it using a combination of 1031 exchange and the Section 121 exclusion to buy a new property that might cashflow better.

However, I know this will be very difficult to pull off and is a high risk, especially since I'm already using a lot of time for my full time job and building up my insurance agency on the side after work.

Sure if you are buying a condo downtown you can probably get away with using a discount broker. 

We have occasionally run into issues with the Internet being down at the STR and it not all going through with a tenant now using a code that doesn't work.
