So, clearly something that a tokenized security is great for and a custom block chain that never lets papers get lost, changes made without approval, etc.They gave me this to read and I found a lot more too. https://www.realestateskills.com/blog/private-money-lenders It is an extremely common strategy, but they want to take it to the digital world.

If it's block construction (less likely, since you said it's a "paper thin wall"), there's probably not a lot you can do, short of framing in a second wall with a cavity in between. 

Indianapolis can vary block to block.

I can look at a block on Google and in-person and know most of what I need to know and more by driving two blocks each way in terms of tenancies and amenities.

As mentioned, my realtor #Cory Robinson found a 2Br / 1Bath duplex on Riley Ave - about 6 blocks from where I would eventually call HOME here in Indy.  

My number one best all time creative financing of a property that I ever did was for a purchase of a empty lot two blocks from the ocean in Long Branch, I was reading the local auction list in my city when I noticed a property that at auction two weeks before that opened at a starting bid of $25,000 did not receive one bid, I went to the auction thinking I was going to pick it up for $10,000, I get to the auction at City hall and when the bidding started for this particular property I waited to see who was bidding, a man started it and I waited until nobody bid to start my bidding, well this man really wanted this property and so did I, when we were at $50,000 I started to try and knock him out by bidding in $1,000 increments instead of $100 increments, every time I bid he bid a $100.00 more, this went on until my winning bid of $66,700 and it was now mine, now if you don't know much about city auctions you do not walk around with that kind of money, a 10% deposit is what this auction required and they give (I forget the exact amount of time maybe 30 to 45 days to pay in full) now comes the creative financing part, I take my high credit card limit at the time of $72,000 (I saved all the 0 % introductory rate checks if paid to another credit card balance transfer and pay off another credit card that had a small balance of $1,000 and overpay the bill by $68,000, the overpaid credit card company sends me a over-payment refund check for $68,000 (that is 0% for six months being that it was a balance transfer offer of 0% for six months) I pay in full for the property within the time allowed by the city, (this was in 2003) I refinance another property that I increased it's value with the creative equity work I put in and got a favorable appraisal that allowed me to park the debt into a 30 year mortgage, the empty lot sold in June of 2006 for asking price of $229,000 with a profit of almost $150,000 after commissions, property taxes and maintenance/lawn cutting.

The one other thing we do is we replace all hinges with invisible hinges; You can buy "non-morticed" invisibile hinges and add blocking to mount on the older style face frame cabinets we often find used.

I know there is high RE tax and know it can change block by block so are there any recommendations of where you can best invest for cash flow? 

We had just over $25k in each of them by the time I had them moved, blocked/underpinned, installed septic, water, etc.

@Courtney Rollins Does this house have exposed brick and on a 1700 block?
