Without cash reserves and solid credit, that is difficult. 

If it's tight or you're uncomfortable with the tenant you have in there from a confidence perspective, especially if this is a first deal, maybe meet in the middle and get a lender at 75% or 77% (doesn't HAVE to be at 5% increments) that wont make you season, and leave a bit more money in the deal, but sleep better.Overall, if I cash flow well, have/keep reserves, and am comfortable I fixed everything in the house, I like to max out the LTV on refi.

There are several benefits of having cash in the bank/liquid reserves versus an open end mortgage (a.k.a) credit card.

If it’s not used, I treat it as reserve funds.  

Having cash reserves gave me the confidence to move quickly on a great deal without losing sleep over unexpected expenses.

If I go BRRRR I’ll refinance with a standard lender.Assuming we sell for $625k which is the ARV and market analysis I pulled, purchased for $345,500 and have $120k in reserves for rehab cost.

I've included an example below to help illustrate this.So different lenders have different rates (which do vary even for DSCR loans) but these are factors they all consider.See example below:DSCR < 1Principal + Interest = $1,700Taxes = $350, Insurance = $100, Association Dues = $50Total PITIA = $2200Rent = $2000DSCR = Rent/PITIA = 2000/2200 = 0.91Since the DSCR is 0.91, we know the expenses are greater than the income of the property.DSCR >1Principal + Interest = $1,500Taxes = $250, Insurance = $100, Association Dues = $25Total PITIA = $1875 Rent = $2300DSCR = Rent/PITIA = 2300/1875 = 1.23If a purchase, you also generally need reserves / savings to show you have 3-6 month payments of PITIA (principal / interest (mortgage payment), property taxes and insurance and HOA (if applicable).

You will need down payment money, You will need cash reserves Money, you'll need closing costs money, and you will need to get a bank loan.

If you have the reserves to pay yourself, I recommend to not purchase the warranty.

Make sure you have enough saved up not only for the down payment but also closing cost, plus some reserve in bank accounts or in other investment accounts!
