That all sounds great, assuming the investment performs the way the example works.  

You need a legal professional who is tough when needed, wise and very experienced.Legal expenses are deductible against taxable income if you're structured properly.Then again, this is the type of expense you should only need to put out once.All that said, of course, it sounds like you need to be dealing with the local LLC-friendly banks. 

In the video I show how I end up replacing most of the suggested comps with comps pulled from Redfin and the justification behind it, but the punchline is that it helps you come up with an accurate number doing what @Hem Kumar said: "...make adjustments for unique features and amenities..."

It sounds like your goal is to get out of the rat race.

It sounds like if we are making verbal offers, I should make sure my realtor really stresses that I am ready and capable to make the offer and have the numbers to justify my offer price, and also make sure the "offer" is reaching the ears of the seller and not stopping at his/her realtor.But I think I'm leaning toward official full package offers with a "heads up" call from my realtor to the seller/seller's agent.

Good way to replace your income. 

., but it sounds like the bank still would need to accept the offer anyways. 

Sounds like a good course for a cheap price.

The septic is bad and needs to be replaced on a property I am considering.

(For example, the dishwasher broke and the landlord literally told us 'you guys buy and replace it and I'll reimburse you' so I got a cheap one on craigslist for 25$...) and that's why @Onna-lisa Kyom is correct that maybe they would sell it for less because it needs so much work.
