(Random theoretical ease-of-use numbers here) Does this mean that If I bought a property for 50k all cash and it's all mine, I can't pull out say 65k if it is appraised for 100k (using 65% LTV obviously) once renovations are done? 

Also, always keep in mind your Passive Activity Loss Account, as this can help ease your mind and open up opportunities you may not have considered  

How can I make potential tenants feel at ease when reading listing, to legitimacy of offering so they feel secure in dealing with me, putting deposits, etc.

It gives you a low barrier of entry to buying (low down payment), you get favorable loan terms, it eases you into property management and lets you manage maintenance issues (hiring or DIY).There are lots of great videos and webinars on BP that go through this process in detail.Welcome to BP!

The condo I did in Ohio was done about 10 years ago and we got a range with controls up front and a refrig that was accessible with ease....a higher toildet, lower bathroom sink and roll in shower...that kind of modifications.I am quite new here and sure would appreciate any ideas or cost estimate that you might know about.Thanks so much....Phil

Should I ease up and wait for the markets to cycle down and get a stronger start position? 

What it does is postpone the inevitable and create tension over a longer period of time.

When your paying cash, the numbers always work - what you aren’t accounting for is the ease/difficult of management.

If you negotiate and agree on a price with the seller your inspection will ease your mind of potential pitfalls.

It is also easier to just pull out a credit card instead of having to deal with cash...I know some will argue that this ease of use is dangerous due to the potential to spend money that i don't actually have...but rest assured, my social awkwardness far outweighs my urge to spend money when I do make it out of the house.
