There should exist a 24-Hour-Notice-To-Vacate procedure for special cases such as: imminent threats, reckless endangerment (causing serious risk of injury to someone else on the premises other than you), inflicting substational personal injury ect. 

Its not cheap to have a property demoed in Detroit, Ex.  2100 sf , two story, between two existing homes will cost approx. 13k, without asbestos and lead remediation - it will take 60-90 days to get utilities terminated, and proper permits issued.

I am currently focusing on promoting "Creative Finance" (Rent To Own, Deposit Finance etc) which is not a big thing here at all and have some new (apartments) and existing properties which are attracting a huge amount of interest.

My first questions to get answered are always:-  Do they have an existing mortgage or do they own the home free and clear (if a mortgage is present, do they need to pay it off for the deal to work)- Do they need the cash or do they want a prolonged income streamAnswers to those questions can help understand some of the key seller motivations.A typical seller financing structure would have a down-payment that would range from $10-$20K up to 10%-20%.Interest rates typically range 1-4pts over residential real estate mortgage interest ratesIf the seller wants long term cash-flow, the term can be 10yr-30yr.   

The more exists you have had in the last 2 years the better the terms get.

I'm a big believer in direct bookings but you'll need to utilize the existing marketplaces first to gain traction then invest in your own site.

This seems like an overly complicated solution to a problem that doesn't exist...

Fitting existing doors to a frame takes some skill, some tools, and some work, but not $150 per room door.

I’m hesistant to flip, because I feel like our current market is SO over saturated with (poorly) flipped homes.

Obviously, you don't need to answer these questions out loud...If you want to build your portfolio, then it does not make sense to pay off the loan on your existing property unless you can get the money back out for another property at a lower rate.
