Rental: HML --> Cash out refi?

[Vickie Y.]

Hi everyone, 

Been on the hunt for SFH rental. Currently have enough to put down a conventional 20% down on a 150-200k SFH. However, I am trying to think for the long-term, and if I am to meet my goal of 20 properties in 10 years, I won't be able to use my own money to sustain this. Furthermore, I doubt any conventional bank will be willing to lend past 4-5 properties.

My question is this: 

Is it possible to use a Hard Money Loan to purchase the SFH rental in cash --> then use a CASH OUT refinance to put the SFH under a "conventional" loan?

So in this scenario: 

Purchase home for 175k in CASH using hard money --> put 10k of repairs into it --> Put tenant in --> ARV now 200k (cash in 185k) --> CASH OUT REFINANCE 200k @ X % over 30 years --> pay back HML --> cash flow off property (rent - new mortgage)

1) Is this just a convoluted way of talking about the "BRRR" strategy?

2) What kind of lender would be willing to do a cash-out refinance?

3) I've heard of "seasoning periods" - does that mean I would have to own the property for X number of months or years prior to being able to refinance? 

4) In the ideal situation, how long does the process usually take from: under contract --> cash refinanced out - and HML paid back?

Thank you again everyone for all of your help and advice!
