We could then make a cash for keys offer and play out the eviction process, if it wasn't accepted.What I don't know is how tough it's going to be to evict this woman, if she doesn't accept the cash for keys.  

If you are inexperienced as a rehabber a 100k rehab may be tough to manage for your first project.

@Christopher TellesYou are looking at about $5,000 per bathroom which would include labor and materials (demo of the old bath, new tub, new diverter and trim kit, new vanity with granite or cultured marble top, new sink faucet, new toilet, new tile surround, new tile floor, and lastly a towel / shower rod).

that's a tough one.  

You can obviously search Google, but a method I've used before in addition to my network is to visit construction suppliers (companies like ORCO Block) who supply builders with construction materials.

I have been spending time studying materials on BP to know more about real estate investing.I plan to invest  in Nigeria and Uae but there are no post ,blogs or articles on BP that i have read so far that talks extensively or give strategies based on this two markets .So the challenge I have is that most of the post on Bp talking about stragies of acquiring a property and rentals does not really tally with the Nigerian market.

I talk pretty tough and stick to rigid rules when I give advice on here, but there are many good deeds I have done, but it was when I had enough money to do so, and it depended on the tenant and how long they were with me. 

I'm looking for material that will stand the test of renters who may or may not care about the property.

Or maybe that the tenant is required to change the filter every x months.But thats going to be a tough one to enforce.

I would rather be in charge and selecting my own materials.
