We normally ratchet the rent up over several months when we acquire a property with a tenant in place.Better to make needed changes right away then keep dropping little bombs, but be prepared to stick to your guns and face the consequences.

There is no set rate, it's all based on the yield returns the investor wants acquire.

Wondering if its a good investment to re-enroll for another 6 months and get the package that includes access for the pre-licensing classes as well as the 90 hour post license class requirement. 

As of the present time, I have flipped three single family residences, and am working on acquiring my fourth property.  

If I pay cash I won't have access to the downpayment $$$ for the next property that I want to purchase, so I would NEED the HELOC.

@Cole MitchellYou can certainly sell an asset by an S-corp to the shareholders as long as the sale is at an arms length transactions.The questions is should you.If you plan to acquire it in an S-corp(you will be forgoing the section 121 exclusion which you said you are okay with) if you are going to just sell it within a year - you should just sell it directly from the S-corp.Transferring the property from the S-corp to you personally and then eventually the buyers will cost more in title work.

Using leverage you could acquire several properties with your 100k instead of 1, which is what i intend to do.Good luck!

Ultimately, we're seeking to acquire long term buy/hold cash flowing multifamily properties (2-12 units... at least to begin) starting in the Milwaukee/Madison, WI area, but we'd be buying from an out-of-state position, since I'm currently stationed out in Maryland on active duty.  

If I get married, can I still acquire 4 FHA loans and my wife acquire 4 more?

If you choose to renovate before renting it out in hopes of acquiring higher rent then that is your decision.
