IE Tenants in common as to 50% each if your putting in equal money.. 

This owner simply bought at the top and is unrealistic which is why it is sitting.The 15k reduction doesn't mean anything if it was already 100k or more overpriced.The only way they are running costs in the 25% range is if they are deferring maintenance on the property.If you have a size able chunk of money like you are saying I would forget the 4 unit stuff.I would buy a larger property where you control the look and feel of the development and will have more upside in equity down the road and also land for possible redevelopment.If you own a little 4 unit among a bunch of other 4 unit properties you generally are limited in resale scope and also are at the mercy of what the other investors who own around you are doing.So if they drop the rents,do a short sale or foreclosure,do not make repairs,put shoddy tenants in to just fill it up then it will affect your property no matter how well you keep yours.Just things to think about.Good Luck

Having properties heavily mortgaged scares lenders away (rightfully so)So basically, buying with loans allows you to increase you networth much quicker if properties are appreciating in equity (forced or not) or cashflow.

It would mean you have a cash flowing property with 25% plus in equity. 

I have about 260k in equity in a rental I have which brings in about 600/month in net income. 

Turner did several podcast on this...look around #150+ for the latest reason you are doing well with 20-25% in equity.

One property in the Dallas area has been refinanced into a lower rate and has grown a little bit in equity.

If you're going to finance a property 100%, you definitely want to have built-in equity to protect you in case the market takes a dip.

Therefore we're essentially locking up $45k for about $10k or so in equity.

You have over $90,000 in equity in a duplex so why aren't you producing a strong cash-flow?
