What are the costs for the value adds, the expected hold time, and the expected sale price? 

@Shakthi Kamal read copy and paste advice below.For cashflow, you'll be looking at mostly Class C properties/tenants.Be SURE you UNDERSTAND what this means or your expectations won't match reality!

On buy-and holds we usually replace all the plumbing with pex, no matter what, because galvanized has a life expectation of about 60 years, so I usually take the sooner than later approach.Stick with hard money, like Mach1 or or MKE hard money (Scott Lurie) as they will not leand on a deal that does not pencil out, so you have the added benefit of someone experienced looking over your numbers.

The real estate investing industry uses "Classes" to rank property performance risk, but there's NO agreed upon industry model:(Here's what we use for our Metro Detroit market:Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

Otherwise, you'll have to go for a hard money lender and expect 12%+.

There are several companies that send letters and some are active on Bigger Pockets.However, I would caution you to set expectations appropriately.1.

For your ~$10K fee, I expect for you to be thorough and clear and make sure that these things are known as it is difficult to see everything on video.

Share a clear business plan with numbers showing expected purchase, rehab costs, ARV, and rental income.

There is no general rule of thumb but you can expect it to be in the range you have listed above.

I expect 30% turnover in a given year, but have seen it surge as high as 48%.
