. $2000 to dig up & replace the old pipes just to remove the cement like sludge. 

They targeted dentists and doctors, then used that as credibility for getting other investors.

Houses built on cement work well with ceramic. 

Not all contractors or investors are equal, nor docta, dentists, and others.

(Can be a lot more if they are fully cement) Best of Luck 

How close is the proposed purchase from the hospital, physician and dentist offices, emergency medical services, etc.?

Private money lenders can be friends, family, your doctor, dentist, neighbor, people you know from work, from business, etc.

Hi Eli,Although some people will just tell their contractor to use "The cheapest" or what is "Cheapest at Home Depot" or spec nothing and let the contractor pick out what he wants.It's best to pick your items using industry standard grading language (for lumber, cement slump, and etc...), or by manufacturer and part number (for paint, faucets, water closets, and etc..).Then work that language into the bid request (and manually verify it is being used on the site vs cheaper knockoffs).Kitchen faucets and shower mixing valves, for instance can vary widely in construction materials, service life, ease of installation (installer time), and ease of service once in service.Also, some manufactures will have grades for items, such as builder, multifamily, hospitality, hospital, homeowner, etc... 

THE light switch that turned on the light to the bathroom, located inside the shower...Redoing the landscaping in my current house I found beer cans as the frame for the cement edging.

I'll continue with emphasis on the part about starting off with true "Private Money" - friends, relatives, neighbors, your dentist, folks you know who aren't necessarily in it for the profits (but who wouldn't mind . . .),  and starting with one property.
