Since their lease expired 5 & 9 years ago(2 separate unit), can I file application with UC township to catch up previous rent increase ( average 2%-3% CPI Consumer Price Index increase)?

I recently sold it and made a modest profit.

This is almost always something I try to do myself unless I don't have the time because it is time consuming if your new at it or doing it by yourself.3- Painting is only timing consuming.

He's more in the upscale niche, however might be able to connect you to another builder in the area if you're looking for a more modest build. 

It is way more difficult and time consuming than most people make it sound, and I have yet to meet a truly successful and honest wholesaler (have met many who are not either).   

A few more seasoned investors have told me, perhaps controversially, that most cities place such onerous zoning restrictions and are completely inactive in aiding affordable house because lower income and lower-mid income residents are such a net loss to the cities, i.e. little tax revenue and big consumers of city services.

@James Cloud What do you mean when by buyer, the investor or the end consumer (buyer of flip, tenant, buyer of wholesale)? 

It was very interesting and I am glad I did it, but it's crazy time consuming (I general'ed it myself ), ties up so much capital and is quite risky actuallly - "spec home" is short for speculation after all.

For the cost of a modest price meal I got about an hours worth of legal advice. 

It's time consuming.
