Shoot the last roof I did, I went to a roofing wholesaler that has all sorts of shingles.

This is not always the case but just wanted to warn you about some of the cases.Generally speaking, you want to make sure you have some sort of script that you go by.

I've received sort of mixed messages from accountants on this. 

Generally speaking they'll all have a niche of some sort be it price/type of asset/ or location. 

To elaborate -- there are so many people on the forum that would be glad to help you without any sort of compensation / NDA / etc.

Just be sure to ask your bank those sort of details. 

What sort of loan should I be looking at to purchase the $750,000 home?

I purchased a home in November 2017 and am putting it on the market March 1st - assuming that it sells fairly quickly, I'll have owned the house for under 2 years and will have to pay capital gains taxes (for reference, CT house purchased at 91k, ~25k in repairs, listing at 170k - I'll be probably renting a place to live in myself as soon as a deal goes through, then looking to purchase a multifamily to rent out within 6 months or so, but very unlikely immediately after closing).I have a sort of two-part follow-up question about this, which is rooted in the fact that I know very little about capital gains and am feeling overwhelmed every time I try to Google/BP search the topic.

I would say the best place to ask this sort of a question is with a title company or if you want to get brave try calling the county courthouse where the property is located. 

I am in the same boat sort of.
