**I understand this data will vary market to market, I'm just looking for ballparks here.

It varies a lot depending on install method, regional area, heck even a specific properties weather exposure. 

The inspection will also vary depending on whether there are kids in the house or not - they don't care about a couple small flaking paint spots if there are not children. 

I know this can vary, but any ballpark figures or advice on funding options would be helpful.

There's no right or wrong way to do this, just varying levels of risk and reward and YOU need to understand what they are for whatever strategy you choose. 

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).

That number varies by state.Virginia - 4Maryland - 5DC - 6

When working with private lenders, the costs for preparing loan documents can vary based on a few factors, including the complexity of the loan, the attorney’s experience, and the geographic location.

And that ARV estimate above isn't a one-off either, varying the radius shows different values for this just-sold renovated home:

Does the market really want nearly uniform full-service brokerage service (often of varying quality)?
