And I am small time(for now) I work out average rents by street and building and what improvements that might be justified by additional rent.

Steven, the idea was to make the deal attractive to the sellers, but how would you restructure it to improve my situation and still be persuasive?

Do a quick search of "newburgh ny crime", in 2015 it made the top 10 most dangerous cities in America...looks like it's improved a bit since then.  

The first option with duct work seems more expensive and intrusive to occupied units.Unfortunately there is no natural gas available nearby to tap into, which is of course my favorite way to heat.Any thoughts or advice in this area would be appreciated.Also curious to know if anyone is familiar with federal or state (we are in MD) tax breaks or incentives for improving efficiency of a building, or converting from oil heat. 

I budget 10% for vacancy and 20% for maintenance/capital improvements.  

There are definitely some decent efficiencies and economies of scale with starting out with multifamily units. 

Your position on this item will be stronger if your lease has language regarding making unapproved repairs or improvements.2)  I think you fill those holes with mortar and move on. 

They have a great platform no doubt, and drive great results.However, they are moving into Hotel deals as they offer a scaling-up and efficiency of time and effort, but the management % they are proposing for a real estate deal is 20%... 

I’ve made substantial improvements to the property (flooring, texture, interior and exterior paint, total bathroom remodel, painted cabinets, new carpet, crown and base, new doors).

There are a lot of moving parts to successfully purchase the land, get entitlements, put in horizontal improvements, put in vertical improvements, get leases negotiated and in place etc.
