@Sean Conroy, this really depends on two things: first, the land zoned in a way that you can subdivide and build more units (question for building/zoning department) and second, financial returns on doing this versus using the capital to buy.New construction certainly has its advantages on the operating side, and can often get a premium to remodeled, older units.  

In the past, the Department of HUD targeted S8 rents to be at the lower end of a rental market.

You can also use Google Drive to store receipts.

You can google how to do it but local hardware store should have all the tools you need.

I still use Stessa for administrative reasons to store documents and it can easily run a Statement of Real Estate Owned and other useful reports. 

If they say you don't need any, I would ask them why (and give a quick call to building department, describing your scope of work and see if you get same answer).

Questions like: How long do you have to store his stuff?  

I leave near Baltimore MD and I have heard horror stories about the tenants AND the section 8 department.

Pennsylvania has specific regulations for these facilities, mostly overseen by the Department of Human Services (DHS).

High inflation means that people will be looking for products that can store their wealth (aka "liquidity"), such as gold, cryptocurrency, or real estate.So why buy real estate during inflation?
