Id imagine you want to at minimum break even if not have some healthy cash flow while you buy and hold.

.- Buyers earn a reduced yield but hold a valuable option.Much in the same way that equity yields are reduced in up markets when bought with put options.How often do you buy/sell debt with put options?

Providing the cash flow will support the loan payments.

If you can afford it, do it and just hold long term.

I share this not to discourage you from embarking on this project with you as a manager, but I flip homes and have seen for myself the incredible savings in time and money that can be activated when you have the right person overseeing the project and who has the relationships with the subs that can make sure to push them and hold them accountable.

Just want to make sure the market rents support the new purchase PITI payment.

Specifically, I am focused on wholesaling as a way to build enough capital to start investing in SFR/multifamily with a buy and hold strategy.

I am guessing when you and your company brought your pm in-house you were in a position that if something did not go right, you had the resources to support the change (financially speaking).

Assuming the repairs come of their current asking price and are ~$40,000, I did a quick underwriting and come up with a 5.7% levered IRR at a 10 year hold period and 6.5% interest rate. 

I work as a civil, but have survey support experience as well.
