DSCR lenders will be able to go up to 80% LTV and require no seasoning as long as there has been documented improvements and the property can debt service at the higher loan amount. 

Of course, any capital improvements you've put into the property would be added to that purchase price which may reduce your taxable gain.But returning to your question, assuming I understood it right, what you're suggesting should work. 

Hi everyone, I am looking to improve my knowledge about multifamily investing (specifically syndications or pooled funds).

I’ve also read that the sales contract must disclose the improvements and the names of the contractors.

These improvements modernized the home, boosted curb appeal, and increased market value.

Buying existing rentals and improving it is another story.

These updates modernized the property, improved its curb appeal, and increased its market value.

There's an interview between Jerry Norton and Gary Pickren on youtube that I feel is particularly insightful.

These updates modernized the property, improved its curb appeal, and significantly increased its market value.

Is this location improving?
