The funds used to fix up the property came from a personal loan that I took out. 

I sent a follow up text asking for the buyer's name, proof of funds. and email so I can send the agreement first if he's planning to double close.My main question is, Is this a common way of being approached by buyers, or every buyer has their own way?

The exchange has to be done with an intermediary because you aren't allowed to touch the funds, but you're past that now...

Just limited in funds to put down, especially if it needs a lot of repairs. 

If you don't, then you could see all your funds disappear and you wind up with no cash flow and no equity. 

I have not invested yet because I am still raising capital but I will eventually. 

New roof, which remediate the mold issue, $8,500.Countered seller with: fixing foundation issues, splitting roof cost, evicting hoarder.Seller in turn countered with $8,000 credit, to use as we see fit.Rents are below market and there's room to raise them even before rehabbing the units.Tear me apart.

No bank will finance it, so you will need to partner with a private money person to fund this.

It works fine with the space.I had mentioned and shown earlier that the ceiling was raised in the one and only bedroom.

When you have the funds and the approval, you can move forward on your first duplex/triplex/quad house hack.
