Hi, are there any lenders that do refinance within 6 months seasoning period while using full ARV for appraisal?

There is no locked rate period like there is with conventional. 

But our offers aren't sight unseen, we will always have an inspection period in our offer.

If I were you I would be willing to honor the lease amount and this person as your tenant for the time period they are prepaying for. 

Since you are likely assuming a contract from the wholesaler, said contract should have an inspection period.

Number of claims over a period of time can create problems for getting insurance or can increase your rate.

These would simply be to determine your taxable gain.You will however have depreciation recapture taxes due, for the period it was a rental, whether you claimed it or not. 

You are in the golden period where you can sell without paying any taxes.

There are also tax breaks should you only own the asset for a five or seven year period. 

My states is very clear: if I accept my tenant's application for rental assistance, I agree to stop all eviction actions until their application is processed and I won't evict them for non-payment of rent during any period ERAP is paying for their rent.
