Most real estate investment will have aspects of both cash flow or appreciation, but be over biased to one or the other. 

I'm looking at fixer uppers that are considered livable (heat, plumbing, etc) and I think my DTI will be sufficient once I get renters on my current quadplex.Just trying to plan ahead, thanks!

Some will do free "owners and encumbrances" reports.

You will need it for your next purchase anyway  

It will familiarize you with the basic terminology and benefits.

A couple of them are big time investors these days with over 40 houses each and have moved up to STRs and commercial properties.Find someone that will share their opinions and suggestions and it'll help keep you motivated to get through the starting period. 

I have some experience buy and hold rental properties, and now I want to do flips, I need investors and I have some that have shown interest, in addition to speaking to private lenders that are willing to fund 70% of the LTV (based on the desired property)I'm seeing a lot of deals from wholesalers, but the problem is, some of them close in 2 weeks and some as long as a month, and they don't take conditional offers, and the good ones fly off the shelf really quick.My question is, how does someone like me close one of those deals within this short period, how do you arrange the equity and financing with little to no inspections sometimes even.I'd like to know how do I prepare myself to be able to close one of these good deals right away when they are offered to me and many others?

They are are not lenders they say they will close your loan and act as lenders they kept my deposit and sent me to other brokers They are fake with no credentials they are a scam

If not, you might want to, then whenever the keyword comes up you will be notified whenever it's being discussed on the forums.

In considering cost, you'll want to look at how much the tenant owes you, and how much time/headache the service will save you.
