I'm not sure I like the idea of charging rent for each spot as this would assume you may be able to increase rents which may or may not be the case. 

What they're wondering is if they could sell their lot to the same developer who buys the tear-down, allowing the developer to get extra value by increasing the lot size.

Increase income, build lasting friendships and networks, give back more then you receive, teach others help others give praise to a higher power, love all mankind.   

I use employment info, increasing population, state of housing market - I like housing shortages, etc. 

Opting for a custodian on a Solo 401k plan unnecessarily inserts a middleman that usually slows transaction times and increases your overall costs.

If I do not desire the tenant or he does not want the increased rent I look for a new tenant for the rehabbed unit.  6) I move into the not rehabbed unit and start rehabbing it.  7) when I am done rehabbing it I refinance it pulling out hopefully all of my invested money (using contractors I usually get my down and part of my rehab cost but if you are doing much of the work yourself I think you may be able to get out all of your invested money 8) Use all that knowledge you have obtained to do it again with less mistakes trying for that homerun investment (I think most experienced So Cal RE investors have the Homerun deal: the type of deal you can potentially retire on).Here is also something you may not know: Commercial RE loans (5+ units) are more based on the numbers of the property than the numbers of the investor. 

It depends on the tenant profile, generally likely-hood of a tenant self performing increases the smaller they are.

We decided not to renew because we had not done the screening piece and there was going to be a major increase in the rent.

It increased so much in value already. 

I too am appalled at the increasing inability to get a second chance in the USA, a country founded,  developed and built on second chances.
