Any recommendation for a good preferably open source rental management software that primarily handles back end accounting? 

As for your question on the hard money lenders - I don't think it matters how you source the equity for a deal, but it's more important how much equity/downpayment you can put down on a deal - i.e. 10%, 20%, 30%, etc...

Still, I realize I have only scratched the surface, not to mention I am arguably using a source that may be misleadingly rosy.

Trying to source a bookkeeper that specializes in STR and vacation rentals.

I personally use my HELOC for down payments on homes and then quickly pay if off, this allows me to always have a liquid down payment source on hand.

socialexplorer.com is good source for demographic research. 

Using 3rd party sources to determine whether someone is "worthy" to rent from you is bogus because each 3rd party source has different, inaccurate information. 

I'm reaching out to this community because I find it to be a valuable source of knowledge and insights, especially when it comes to real estate investing.I've come across a potential real estate investment opportunity recently, and I'm eager to gather some feedback and insights from fellow enthusiasts and professionals in the field.The property in question is located in Central Florida, in an area that I believe holds significant promise for future growth and appreciation.

Can you share the source of that information about not being able to invest in certain states using your ira LLC?  

As far as buying the home under DSCR it can only be used as an investment and not a primary home.The seller cannot gift you or pay your down payment because the banks will "Source & Season" the funds.
