Hi Lynette, I'm a Managing Partner at a company that does Full-scale flipping, lending, development, and portfolio acquisition, amongst other things! 

Line of Credits (like HELOCS) allows access to a set amount of money up to a pre-determined limit and it is revolving.

I own a home improvement company and also completed a flip with great ROI.

I would try to subscribe to Angies List to determine a suitable mortgage company.

This will be some management company, right?

If you are syndicating or partnering with other investors to fund a Sponsor's deal and you are a company doing this (LLC, partnership) then get a PPM attorney and file with the SEC. 506B is easiest but if it is really risky...then 506C is best. 

I look for density plays that can be executed in an infill setting.

In our experience, the #1 mistake landlords make when selecting a Property Management Company (PMC) is ASSUMING instead of CONFIRMING.

Self managed HOAs are usually undercapitalized so you want to take a thorough review of the condition of the community to make sure there isn’t deferred maintenance because you might get hit with a special assessment if the board isn’t setting aside cash for those capital improvements.At face value, taking into consideration my typical financial objectives, I wouldn’t do this deal unless it was a much lower price.

I called my local insurance company, as well as two major companies and was told "good luck."
