I was left in limbo, accumulating massive losses the entire time.After eviction, things got even better (sarcasm alert).Huge repair bill ( as expected )Of course the 15% fee for managing those repairs.First-month rent for the next lease?

and that was owner occ.. todays rates are pretty normal actually. what you can do if you want though is find a really good HML and let them place a loan for you making 10 to 12% while your wait for things to change to a situation that you feel you want to move forward be more net return than buying a rental thats for sure. of course no tax bene's but there really is not that much tax benefit on one rental.. so just some alternatives. 

Leverage and invest at 40x $100 000 properties ($20k down + $5k closing cost, 30 yeas fix rate loan) with a return of 10% where you have better asset protection (my keeping lower equity and higher bank position), you are hedge against inflation (agree with me, in 30 years $1 000 000 purchasing power will be less compare than $1 000 000 today) Here is how looks mathematically:1. 10% on $1 000 000 (10x $100 000) = $100 000 / annually - No interest tax deduction- No loan paydown benefit2. 10% on 1 000 000 (40x $100 000) = $400 000 / annually - debt service + full tax benefits+ loan pay down+ hedge against inflation for 30 years+ better asset protection (by maintaining lower equity  position)   + (not guaranteed of course) if appreciation happens, it happens on the all full asset amount, example:If appreciate 10%:In case "1" you will have 10% on $1 000 000 = $1 100 000In case "2" you will have 10% on all 40x properties (40x $100 000 = 4 000 000) = $1 400 000As far as cash flow, as long you buy "right" CAP 8% and higher you will have stronger cash flow on leveraged asset + all additional benefits.

Is it worth getting Bob Diamond's course on 'Tax Overages'?

They were simply the king of online bookstores.
