This allows us to invest more money and increase our wealth.

I know that the auctioneer has the right to bid to increase the price but don't know what to do.

My lease agreement has a clause that, the tenant accept the house current as-if condition.

Deals can be found in "No Interior Inspection" properties if I catch the occupant early on (like day-of-listing), but otherwise, our REO properties are bid up too high for the risk taken and condition. 

On MLS, I see some properties in an area have $3k or $5k increases monthly last few months.

It's an asset which has a depreciated cost basis which you increased by deferring gain from a prior proper by way of a 1031.

Add 900 sf for an increased value of 100 k?

Here on BP you can do that by adding a picture to your avatar.Understand that beyond understanding the technicalities of rules and regulations, real estate is about market conditions and helping people to get to yes.Get to know your target market like no one else.Develop your ability to empathize what's going through a buyers head and a sellers head and figure out what you as a real estate agent can do to address concerns.Neither of these are limited by your age.Good luck!

Last time I did an eviction in Jefferson County, I was going through the paperwork and remember seeing that the notice period increased in length with the amount of time the tenant had been in place, while the paperwork for Adams County did not have that same specification.  

not doing the work yourself if you find bad things when demo is done could REALLY increase what it will cost to flip thisI am really impressed with the answers you receivedMaybe post up every room and get feedback lol
