Look on rentometer.com to get an initial idea. 

The borrower and the asset itself.Borrower:Your credit (are you a trustworthy borrower), are you capitalized enough to float this project/ cover the debt, track record (borrower/ contractors experience).Asset:Comps (as-is & ARV), LTV metrics (lender can help verify these if you have questions), detailed budget and scope of work, tentative schedule, exit strategy.Of course any lender/ partner will dive in a little deeper after the initial pitch but if you have all of the above ready for your initial conversation it will go a long way in getting deals approved/ partners on board.

Okay.The cost basis for an inherited property is when the property is initially received.

We have narrowed it down to a duplex in very bad shape, but have a contractor bid to rehab and add a studio in the attic.We have used the BRRRR and have great pos cash flow, even in initial rental.

On the other hand, these tenants have been fantastic (my best so far) and renovating with them present would help generate more goodwill and perhaps lead to extended tenancy and other network benefits (They are both nurses and may have co-workers who are looking for apartments). 

Here's the scoop:The house has been a rental for @ 6 years with decent income; clearing @ $6k + annually; no mortgage; current market value @ $160kI have probably broken even at this point with initial cost and all (many many) upgrades;  have no idea what the tax situation will be if I sell; would not be able to use 2 year personal residence - no cap gains rule.  

As for my thought @Jordan Hamilton the South Florida market on a whole is probably getting near the seventh inning stretch to reference baseball.I only hold SFR and that is my thought, I hear the multi-family game has been fully priced for some time now.In the end, if one is buying to hold long-term and generate monthly cash flow then as long as the numbers work and it cash flows positive it might now matter as much.Be sure to work those numbers though: vacancies, maintenance, etc. 

We have an automated system using some coding applications (self made) to generate leads from various sites, coupled with help from some VA's.Once the data / lead list is created on a spreadsheet/google sheets, we pull into Freshsales as our CRM. 

In order to grow rapidly in RE, you have to use leverage as much as you can, which is exactly the opposite of the approach you described in your initial post ;).

I've generally purchased properties that had the potential to generate additional NOI and I've managed them such that I've forced quite a bit of equity, however, my main focus is cash flow.
