Either simply overpriced and sat for months not willing to reduce the list price, but willing to take a (reasonably) lower offer.

For a beginner, I'd suggest you start with something small like a bathroom.

Even if they are on mls so one is going to end up making an offer close to market value.

Just ask a lender if you can do the project as tenants in common with 3/4 and 1/4 ownership with you being a non-occupant co-borrower as @Joseph Chiofalo suggests. 

Quote from @Greg Flannery: Trying to offer ex an amount for condo were both on title and mortgage for.

To save cost and headache I suggest to keep your property and his property out.

We are open to offers creative or not.

I would not venture beyond your skill set and suggest you risk harming yourself, such as getting electrocuted, however, once you have completed your work, have it inspected with the local building inspector.

I own a cleaning company and was going to offer insite. 

I would like to raise more capital for purposes of submitting all-cash offers.
