Logically it seems to make sense to buy the SFH, but somehow I get the sense that it would be a lot harder to continue the house hacking dream if I go the SFH route.  

I had the regular home inspection done.

I would suggest going the wholesaling route until you build up enough capital to do a fix n flip or save enough for a down payment.

Hi, I'm in the very early phase of looking to buy a SFH rental up to 75K. I currently owe 280K on a 400k mortgage at 4% with excellent credit.  Considering 3 options to finance the purchase of the rental: 1) HELOC. 2)...

That's what I was thinking, It is in an amazing location, right on the bus route, across the street from convenience stores, a newly built Walmart, major shopping centers, parks, schools, and the Cardinals stadium.

I am wondering if I should bite the bullet and get all new windows or if there is an alternative route??

The ideas are endless - pause a little longer before going with the storage route. 

In any case...the lower rate with PMI is a better route to go.

Disclaimer: I am not a professional electrician.Yes, you have to provide a GFCI outlet in a bathroom.For new construction, I think the bathroom has to be on its own 20 amp circuit, but I'm not sure that's always been the case; it may have been 15 amps in the past.Like @Donald Howaniecsaid, you can get a combination GFCI and switch that fits in the space of one "regular" switch or outlet. 

My route for investing out of town has been to go to properties so far off the beaten path (Northern New Brunswick) that it's the extreme opposite of BC.
