My only concern about firing them right now is that we don't have infrastructure in place for someone to take over.

You could always run the deal past a lender and see what terms they have and or check in each year with a lender to monitor rates and options while you have 5 years with the seller financing.

If we don’t have direct marketing infrastructure, are there any other ways to get leads?

Atchison tends to be a bit further out geographically for our appetite, but we monitor it from a higher level for low cap investment indicators in case needed.   

If there is no way to throttle, how can i monitor the energy consumption from each tenant? 

I have created a budget for us that I monitor month-to-month.

If my tenant's usage is 600 gallons per day, on the high end, instead of 344/day, the actual usage, my water charges would run almost $1,200 every 3 months for the duplex, or $400 month for the duplex, coming to $200/month per unit.I just recently change the billing to monthly to more closely monitor things.

I can go into a market with a competitive advantage utilizing my skills & infrastructure etc....With bitcoin you are just another anonymous Joe.

Great realtor to back into values2. builders to get idea of vertical sq ft costs3. land planner/ engineer for the city county state permitting process.So I find out the big rocks.. then hone in a property that seems good.put it into contract .. then I hire a consulting engineer land planner to do a feasablity study.. if your an existing bigger client they usually do them for free .. in exchange to get your work.but most likely you will have to pay for it.. 5 to 10k is what you can expect.this will include what needs to be done for regulatory approvals.will include environmental hurdles IE who you have to hire / do yo need a wetlands study etc.basic take off on infrastructure costs..

I LOVE section 8everyone has different experiences and part of that is local S8 infrastructure.
