Another investor has a subject to on a property.

May try to acquire the property subject-to.

I assume my offer is subject to inspections and due diligence, so if I make an offer, should the inspection period be on the longer side?  

Rent might not actually save you on self-employment taxes anyway since renting to your own business can be considered nonpassive...unlike renting your home, which is definitely NOT subject to self-employment tax.  

The subject says it all!

Private message me if you need any more help on this subject.  

In those situations though, I am still more partial to a subject-to deal because you actually gain title.

Control and RollWith the owner being elderly - it would be best to discuss your proposal with their personal representative or relative - shouldn't negotiate with elderly seller - you don't want anyone to think you are taking unfair advantage -Your offer should be that you will offer to purchase the property subject to an assignment to third party - you will need right of possession - a long study period.

or is subjective decision entirely based on current situation (financial, goals etc..)? 

I'm thinking of possibly buying a 3 bd, 2 bath, SF home in Mechanichville, NY but I can only do it with terms (seller finance, subject 2, or lease option) but I need your advise.
