I'll start with one item and give you more later if you want. 

Some people like the flipping business model, I just prefer buy & hold. 

I changed my policy for lienable items because of this.

Sounds like a solid business model.

@Francisco Soto  I believe it's only 30 days for the bureaus to respond or remove the item. 

I am going to just do a simple buy and hold model with multi family units.

I know my lender wants the line item complete and installed before paying out, so I have learned to break down the budget into smaller chunks plumbing  rough in and then plumbing  fixtures etc.. it usually takes less than a week to get paid some lenders just have you submit pictures or livestream the inspection.  

As to terms and conditions, you'll negotiate the various conditions you normally would with a seller, such as earnest money amount, closing dates, due diligence dates and any other special conditions.Most real estate attorney have addendums to standard P&S contracts, namely, the contract is not assignable, and is the first item on their addendum, otherwise standard contracts is assignable by default.

It is just a quick check to see if you are in the ballpark or not and then you do an itemized calculation of all expenses, rehab budget and ARV to see if your ROI, cash on cash, IRR, etc meets your desires/goals.Typically, when you are dealing with properties under $200k and especially under $150k, you definitely need a 65%/70% or better deal to make that profitable as you have less economies of scale, lower profit margins for the oops and what ifs, etc.

Smaller items I'll generally let the tenant coordinate a time that works for them.
