Have no idea of that monthly/yearly cost.Tenants pay electric.Building has been updated in the past 10 years, also has coin washer and dryer in basement.What do you guys think this is worth based solely on the numbers?

Coin op is one way to go but you will never make money with a duplex, it just keeps them from abusing you with sharing them with friends and family.

Depends a LOT on your competition and what you are targeting.I could rank for "sell my busted up shack in nowhere, GA" in a month because nobody else is trying to be there.It would take a year or more and real money to rank for "we buy houses" There are companies out there that are spending massive coin on adwords on some searches in our market, I guess they are selling leads or something.I'm 6 months in for "we buy houses atlanta" and am  at 80 on google and 40 on Yahoo and am spending some decent money to be that far up. 

That said, things do change so neither side of the coin is uncommon.

It doesn't make sense for a coin op washer dryer in the basement of a duplex.

It's pretty much a coin flip, and not something you can base your decisions on.  

Under a full guardianship that means we are untimately responsible for everything, income, expenses, housing and medical decisions, taxes, debts, mortgages, wills and estate planning, suing or being sued, investments, real property, unique asset liquidations like oil/gas leases, coins, fine art, notes, cars, foreign real estate, boats, wine, financial exploitation investigations including forensic accounting, criminal and civil trial testimony and recovery of funds when we are lucky, budgeting for liquidation of assets in order to fund medical and care expenses, (I could go on for hours); basically everything you can think of in your life... imagine someone else having to do that for you because you're incapacitated.In my work I'd estimate I've been involved in the sale of 300-400 properties, maybe 100 probate cases and many hundreds of guardianship and DPOA cases.  

So I am not being a Debbie downer here just spelling out the other side of the coin its not all Silver Oak Cabrenet and Roses....

Clean up exterior, freshin up exterior paint, put ownings on, do easy maintenance landscaping, add a coin operated laundry for additional $100 per month at $1.50 for washer and dryer each, increase rents in between tenants or at anniversary dates. 

So you're on the other side of that coin now, and should be giving them one of these.Build that into your interest rate, if you want to effectively have it covered by the borrower.
