Roots can damage water and sewer and the property itself 8.

You will just have water in your basement all the time.

How painful would it be for you to have to pay $1000 for a new water heater 6 months from now if something like that happens?

people dont realize plumbing isn't meant to dispose of anything but water waste and tp. 

Mine has roof, floors, appliances, hot water heater, hvac, exterior paint or siding, bath and kitchen remodel, etc.

Engineering , store , pool pond , roads , water, sewer , electric .

The owner pays for gas and water.

Here's my breakdown of the current prop im looking at:Listing price: $130kunit 1: 3BR/2bath 1329sqft $700monthly rentunit 2: 2BR/2bath 1329sqft $700monthly rent2 car garage used by both tenantsexpenses: 239/month taxes, 200/month water bill, 100/month insurance + umbrella policy, 50/month garbage, 5%/5%/5% for repairs vacancy and capXWith the current rents of these long term tenants it makes $132/month cashflow with a 4.34%CoCROI.

If this can be done w/o a building permit then step one.3) you will need water in both units.

Also look at water delivery capacity and sewer capacity as well as potential parking issues.Checking the zoning to be sure they allow a duplex would also be a good idea.Good Luck!
