Purchase price maybe $120,000  a door, that seems high to me for 70s product, but I just don´t remember prices at that time.   

--------------------------------------------------------------------------------------------------------Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a Class A property in Class D area, what quality of tenant will you get?

Now with scope creep anytime you open a wall expect its going to cost more. if you are doing paint and carpet that is one thing but the moment you start renovating bathrooms etc. expect the cost to increase as you do not know what is behind those walls.

Both figures were 0.1% above expectations.

They don;;t have to they learned.- So few pre foreclosures / BK's.   

DSCR and hard money makes this pretty easy, but you would still be expecting to put down 20% on DSCR and a bit less on hard money. 

I would suggest looking up similar rentals in the area to see what the trends are and what features are offered at the price point you are expecting.

That said, expect to deal with a fair amount of fluff leads.The two best strategies I’ve found are inbound methods: direct mail and Google Ads.Direct mail can be expensive, but it can also yield highly discounted properties.Google Ads, on the other hand, doesn’t require data extraction like calls, direct mail, or texting.

. - I think prior to a walkthrough the seller has little/no relationship with you as a potential buyer, so I wouldn't expect more than a rent roll and a list of expenses.
