Hey There - very generally speaking, you need to present the vendor with a Sale Tax Exemption Certificate, and these are specific by the state you operate in.  

Should I put the title in my company mane and then get rehab loan, or can I do it ones, Tax certificate will go one sale in two weeks.

Hello, @Eli M. have you attended the free Section 8 seminar and the subsequent Section 8 certification course for landlords? 

What you should consider part time is real eastate back tax certificates and past due tax deed sales.

Most of the posts here are asking where to find contractors, vet them, or referrals, personally I think by giving these files to them but using them carefully will help you vet if they are flaky or not, companies or GCs that know how to fill these and can comply to this will be a bit pricey, but I am 90% sure that they are of medium caliber and will be reliable than your "2 guys with tools".Files Uploaded:CKCC Daily Sign In Sheet - MOST IMPORTANT DURING A FLIP CKCC Project Budget Sample CKCC TEMPLATE Payment Application Sample CKCC Invoice CKCC Conditional Waiver and Release on Final PaymentCKCC Conditional Waiver and Release on Progress Payment CKCC Unconditional Waiver and Release on Final Payment CKCC Unconditional Waiver and Release on Progress Payment CKCC Residential Improvement Contract - Rehab Contract CKCC Residential Time and Material Contract Notices After Contract Signing CKCC Certificate of Completion CKCC Quote Request Form CKCC Purchase Order FormGood luck and happy hunting!

Just wondering what certifications were needed after flipping a house such as electrical, structural, plumbing, etc. that must be met before you can sell the home?

There is no contractor "certification" from FHA, just an approval from the Lender.

If you get a loan at some LTV (typically 70-75%), then your C/C can be compared to any economic investment, eg money market funds, certificates of deposit ... 

Permits and guarantee certifications are present.

However, there are some Red flags in the listing, it says it can be a duplex, which means it does not have 2 units on the property and the house can be added to to make it a duplex. plus it also says the buyer is responsible for certification and repairs, it may need more repairs then what is in the pictures plus again that seems to mean that the units are not safe to rent and not legal to rent and will have to be certified as such.
