The assumption of your plan based on your notes is that: you're planning on subdividing the lots, creating a development agreement with the AHJ for the land, CC&Rs, any necessary utility/landscape/road/streetlight district annexations, building out the master development infrastructure (water, sewer, power, telecom, roads, curbs/gutters, sidewalks, landscape/stormwater detention, streetlights, fire hydrants, driveways, traffic signals, etc.) and then developing each individual lot.

The future for high Assessments and increasing Property Taxes to pay for infrastructure is everywhere.

If you wanted to keep the tenant you would serve a Cure/Quit notice to them to stop subletting and then you would have to monitor the house closely for awhile to make sure they aren't using it as an airbnb again.As far as losing this tenant, not much of value would be lost if they moved out.

Especially because at the end of the first term the building and infrastructure becomes property of the landlord. 

Finally, you'll want to talk to the utility provider to see how long it has been on the property, where their existing infrastructure is, where the laterals are on private property and what their future use plan is for the lift station. 

The city & state also just passed a big budget for an infrastructure project redoing highways and roads which will increase traffic to the city & create more jobs.
