I have seen a lot of investors get stuck with a Heloc that they opened up and due to a small mistake find out the bank cut their heloc limit in half or in some cases closed the account leaving them with a balance to be paid off before they could even finish a renovation project.Heloc rates are much higher right now versus a 30 Year cash out refinance by over 3-4% in some cases higher depending on credit score, CLTV, and loan size.

Each is about the size of a large plastic container or shopping cart, and they mount right to the wall.

These items are important so that you can budget accordingly and price the deal correctly.What size properties are you focusing on?

I have been looking into Legacy Homes.What size or type home did you buy?

The pitfalls are obviously bad neighborhoods (easy to gauge talking to brokers or running crime maps) and also find the right property manager depending on the size and class of the property. 

Maybe put some of that into a money market account or the stock market, so if an HVAC does go out in 2 months you can pull out $4-8k to replace it (depending on size, location, etc). 

The easiest way to increase your bottom line with a residential rental property in any city of minimum size is rent it out fully furnished.  

The brands I've been bid on have been:Eco WindowsCGI Sparta SeriesLawson IndustriesESWindowsAssuraAssura is from home depot, main advantage i've found is that they have a quick lead time of 4 weeks, compared to everyone else saying 6-8 weeks.CGI I heard its a reputable brand with a good warranty Lawson, cheapest quote but Im' hearing has a huge lead time now and they have been messing up peoples orders with sizes or specificationsES Windows, comes from Colombia and I heard spare parts, replacements and customer service is terribleEco, I haven't really heard much about but price seems close to what I'm being quoted for CGI Spartas Anybody on here with more experience that can help me narrow it down? 

Even better, get some self employment activity and sponsor a solo 401k then no UBIT on leveraged real estate!   

Depending on the size of your portfolio, I suggest considering either "PROPERTYWARE" or "INNAGO":Propertyware is ideal for larger portfolios, offering customizable and automated reporting features.Innago has been very effective for me, enabling property marketing, conducting screenings, and managing rent and maintenance requests.
